As the Glowforge designs in the app have lovely full-color photos attached to them, how do we accomplish the same with our uploads? Have a photo with the same name as the upload in the same directory on upload? What are the requirements of the photo (size/depth, filetype)?
The designs provided by GF have features (such as thumbnail images and pre-selected scores) that are not available to end users. AFAIK, there is no way to accomplish what you’re asking. YMMV.
