We've been working the past couple months (read our blog post) on improving the way we store and handle the animal pictures you upload. From redesigning how we store them, to how (and when) we resize them, we're working to provide you with more options.
It's going to take a while, but we'll have more picture sizes available soon for the Toolkit, API exports, and our Website service. We're even trying to upload the highest quality images to websites like Adopt-a-Pet.com and Petfinder (to the extent they can support them).
This past week we experienced some issues with the way we were uploading pictures to Adopt-a-Pet.com, so some pets didn't have any pictures for a few hours... and we do apologize for those growing pains.
There will probably be additional times when pet pictures disappear for a short time while pictures are reprocessed. If you notice any issues, please contact RescueGroups.org Support, although if you wait a couple hours, the pictures should reappear on their own.
Thank you for your patience and support!
