images not uploading

Hello, thinking what I'd do, I'd try opening them in another editor program like Photoshop, to see if they don't have any problem, and would save in another safe format, just to test, as I said (even renaming and saving it as another file might be helpful), if you haven't tried that, wanted to say that's what I'd do. Let's see, maybe another expert/designer might have another suggestion, since I've never had that issue. Happy designing!
