When I upload images from my phone, they say they fail the security check. Every time. They are just photos from my camera. Is there some sort of EXIF check or something? I know phone photos tend to have a lot of extra junk EXIF data, like I think my location is active, etc.
Or maybe resolution? (over 4000px?) But swear I've seen huge images here and I've uplaod 4k UWD images.
