Moving through the exhibition halls

  • You can move through the 3D spaces in different ways:
    using the arrow keys on your keyboard (forward/backwards and rotate left/right)
    or by holding down the mouse button and moving the mouse (resp. your finger on a touch screen).
    If you also hold the Shift key down, you can pan the screen horizontally and vertically instead of moving;
  • Double click on an artwork (on the wall or in the catalog on the bottom) and you will automatically be taken to its location;
  • Click anywhere in the room and you will automatically be taken to that place;
  • Click the Play button in the top toolbar, to start the guided tour, which will take you to every artwork and pause for a while.


Register, test and (un)subscribe

  • Registering and curating in SandboxGallery is free for an unlimited period of time and tries. But in order to publish an exhibition (make it available for others to see), you will need to rent the gallery (single rental plan) or have a Flatrate (plan for multiple gallery spaces plan).
  • Use your login credentials to sign in to your personal account in the editor (click here to login).
    If the plugin is not already installed on your computer, you will be asked to install it at your first visit. It enables your browser to display 3D content.
  • Select a gallery and start curating. When you are finished, click the “Publish this exhibition…” button on the left of the screen, add the needed information (cover picture, artist, description, medium, etc.) and click on “Book a flatrate” or “Rent gallery”.
  • If you’d like to have a flatrate for multiple exhibitions in any gallery, you can also do it directly without opening an exhibition: open “Account Settings” and go to “Upgrade your account”, where you can select from all available subscription plans (both flatrates and single-gallery rental plans).
  • After accepting the terms, the PayPal website will open. Log in to your PayPal account and create the subscription.
  • Once created, wait for the confirmation email from us and return to the editor. Depending on your choice, you will be able to create and publish a number of exhibitions (in case of a flatrate), or you will be publish your single exhibition.
  • To publish your exhibition, enter the specific exhibition, click on the “Publish this exhibition…” button on the left and you will see the “Publish exhibition” button.
  • Note that you can have several active rental plans and/or flatrates together at the same time. Together they should cover the exhibitions that you created, otherwise your account becomes limited and your exhibitions cannot be viewed by visitors any more.
    As an example: if you rented 3 galleries, you can, at any time, cancel the subscriptions, and cover the 3 galleries by subscribing to a flatrate instead. You could also cancel your flatrate and start single-gallery rental subscriptions for each gallery instead. How you combine plans to cover your usage is up to you.
  • To end a subscription, go to “Account settings” section “Active subscriptions”, then click the “End subscriptions” button. This will open up your Paypal account. There you can cancel your subscription. Search the recurring payment to SandboxGallery, click “Details”, then “Cancel”. The subscription is now canceled, no further payments will happen (you will also get a confirmation email from us). Download instruction PDF.
  • Last but not least, don’t forget to fill in all relevant data in your Account Settings, e.g. your public profile information, for that interested parties can contact you, can find out something about you and your work.


Uploading and placing images

  • Create and open your exhibition (from over 20 exhibition rooms, select one (or several) that you like and suits your work in terms of style and size).
  • Upload all new images, one by one, into your artwork catalog using the folder icon at the bottom of the screen:
    Click on the “Artwork Catalog” icon, then create or select a folder, e.g. “My Artworks”, click on it, then select the “Add Picture Artwork” action icon and you will see a form.
    State the size of the work, the medium and the title of your work in the dialogue field. Upload it as a JPG or TIFF or PNG file.
    The resolution should be around 2048 Pixels and will be automatically reduced if larger (maximum permitted file size for upload: 16 MB).
  • The images can be re-used in all of your exhibitions. Changes to the information of an artwork (e.g. renaming it) will affect all images in all exhibitions likewise. However, you can have different sizes per placement, and you can place images several times even in the same exhibition.
  • After you have all pictures in your catalog that you want to place in your exhibition, go back to the editor, open the Catalog and folder, grab an image and place it on a wall using drag&drop. The distance measures displayed next to it enable perfect fine-adjustment to the inch/cm.
  • Alternatively you can move the work across the wall in centimetre increments using Ctrl + arrow keys (or Ctrl+Shift + arrow keys for 10cm increments), or enter the distance information in order to position it exactly.
  • Switch between Inch or Centimeter in your “Account settings” (see the checkbox in the “Account information” section).
  • By default every change in your exhibition is being automatically saved. You can deactivate this feature using the icon in the left toolbar, but don’t forget to regularly save the exhibition, to protect yourself against potential loss (e.g. due to crashes).


Adding frames, mounts and mattes

  • Select an image on the wall by clicking on it. In the settings, click on the Frame Profile menu item. There you will find a selection of frames. You can also select DIBOND, CANVAS and other frameless formats (to do so, select Frameless in the second row on the left).
  • You can then change the width, depth and color of your frames and mounts via the section “Size & Color” (there you will find settings for Frame Strength, Frame Depth, Frame Color).
  • Each image is automatically displayed with a matte/passepartout (Side Spacing) when placed onto walls. You can edit the matte or delete it. To do so, open the “Size & Color” section, then override the “Side Spacing” information (zero in order to have none), and select a “Spacing Color”.
  • To save time, you can give several pictures the same frame. To do this, select the picture with the required frame and click the “Set as defaults” button in the settings. The frame style has now been saved as a template. Click on “Apply Defaults” to transfer the style to other pictures.


Adding information

  • To add information to a single picture (title, medium, size, description, selling price): Select the relevant picture in the exhibition room by clicking on it. You can then enter the information in the settings form (scroll down).
  • To record information about the entire exhibition (caption, artist(s)/curator, introductory text (Info), medium, copyright, link to your website): Click on the Info icon at the bottom of the screen and enter the information in the settings form. The introductory text is particularly important as it is the first thing that visitors to your exhibition will see. The fields mentioned must be completely filled out before you can publish your exhibition.
  • To specify a cover picture for the exhibition: Select the picture from your exhibition that should appear as the cover picture. In the settings, click on the “Use as exhibition cover picture” button under Info.
  • To specify a profile picture for your account and profile page: Select the picture from your exhibtion that should appear as your profile picture. In the settings, click on “Use as public profile picture“ under Info.
    If you want to select a profile picture that is not in the exhibition, upload it to your My Artworks folder, place it on the wall, then select “Use as public profile picture” and delete the picture (waste bin symbol).


Guided tour

  • SandboxGallery enables you to give guided (audio) tours through your exhibition. To take a tour, visitors simply click the Play button at the top of the screen. The exhibition now runs in the order you have specified and any audio commentary is played.
  • There is no further action required to activate your guided tour. It is automatically organised when you hang your exhibition and can be selected by visitors.
  • If you want to change the order of the tour, you can place the works in the required sequence. To do this, select a work by clicking on it, then use arrow icons on the very top of the settings to move it to the right tour position (see how it changes its position in the catalog listing at the bottom of the screen).
  • It is also easy to offer your visitors an audio tour. For example, record a 30 second explanation about each work and upload it as an OGG sound file (MP3 will be available in the future, for now you will have to use your recording software or other tools to convert your sound files). You can see an example of this here.


Publishing your exhibition

  • When you are happy with your exhibition, you can publish it for others to see. To do this, click on the Info icon at the bottom of the screen to show the exhibition settings. You must fill in all the fields such as title and description in order to be able to publish the exhibition. This information will be displayed on the website and at the start when a visitor accesses your exhibition. Make sure that you have also assigned a medium (photography, oil painting, etc.), artist and curator name.
  • Click on PUBLISH NOW (resp. RE-PUBLISH NOW if you published it already and made changes). Your exhibition can now be viewed by visitors. Whenever you do any changes to your hanging and want to make them publicly visible, you’ll need to RE-PUBLISH your exhibition. You can unpublish your exhibition at any time by clicking the TAKE IT DOWN NOW button.


Tips and tricks

  • You can share your exhibition and invite friends, customers and collectors to visit it. Send a link by email or share the exhibition via Facebook, Twitter and other social networks via the integrated buttons. To obtain a link to your exhibition, click on the Info icon at the bottom of the screen, then on the “Get link to exhibition” action in the toolbar of the settings box. You can share your exhibition even more easily when you view it on our Home page ( and then select Share Exhibition at the top right of the menu.
  • Use the exhibition software for editing, curating and experimenting. In just a few seconds it enables you to test out and optimise different editings and hangings. However, if you use SandboxGallery to prepare an actual exhibition, you can determine the right picture selection, format, number and positioning before you produce your prints.
  • Our community platform gives you greater publicity. On our Home page (, collectors and art lovers will find an increasingly large selection of excellent photography and art which they can view and purchase. Become part of our community.
  • If you plan to make a semi-private exhibition, that is an exhibition that you can share with people (via a link), but which will not appear on our website, then you can uncheck the option in the esettings saying “Feature this exhibition”.
  • On our Home page ( you will soon be able to sell originals (limited editions you print and send yourself) and prints in different formats (open editions produced and sent by us) at prices you set yourself. From summer 2014, SandboxGallery will also be offering a print-on-demand program in which visitors to your exhibitions can order prints in formats specified by you – we are responsible for the production, dispatch and payment collection. You don’t need to worry about it any furhter and will receive a commission on each sale.
    For now you can already add price tags to your pictures, which visitors can see on the website or in the exhibition. To do so, log in to the editor, select a picture on the wall and add offer(s). Interested buyers can then easily contact you.
