An increasing number of shows accept only digital images using Juried Art Services or ZAPP™ software. All images must be formatted properly for successful uploading to their online jurying systems. It can be confusing to sort through the specifications for each system.

I can prepare your new or existing images for ZAPP™, Juried Art Services, or CAFE digital jury systems, or you can prepare your own using image editing software and the specifications below. 

We have studied the requirements for ZAPP™ and Juried Art Services, and compiled the information from their respective web sites into a chart below. In fact, we are one of a handful of photography services recommended by ZAPP™!

Note that ZAPP have relaxed their specifications to allow 1400 pixel images, however this will result in a smaller image surrounded on four sides by a black border. The instructions on the ZAPP web site indicate that black masks are no longer required for non square images. However, for shows that use projectors for jurying it is recommended to continue sizing your images to 1920 pixels on the longest side, and adding the black masks to create a 1920 pixel square image.

JAS and most other shows will accept images formatted to 1920 pixels square, which should allow artists to submit ZAPP formatted images. If you are applying to a show that is using a different format I will be able to help you.
