As for collecting images, I do have a GitHub repository set up, and I can setup a script to update any new images in the repository into my RoboFLOW project, which is where I’ve been annotating images, both manually and with their auto-annotation tool. With RoboFLOW I can community source annotations/annotation review, but not have other users add images (as far as I can tell). I might look into both the programs you mentioned though.
As for collaberating with Limelight, I’ll send them an email asking if I can, but seeing as there’s no way to download the collected images from that link I’m not entirely sure if they’ll let me do that. I will add all the images I have downloaded at regular intervals however, so even if I can use their data, anyone using Limelights stuff can use the data I’ve collected.
