I tried Batman, but it didn't work. I think my computer is just too old. It's an eMac. No one these days have eMacs.

MB: I tried that. Batman: I could try to do that, it's just that my computer is SOOOOO old.

Hmm, try copy-pasting it to a new file, and save it as .PNG? Maybe it is just that one file, if not then you can try converting it to another file.

Try converting it to a JPEG.

firefox. It was in the right size, but it claimed that it wasn't like, PNG, which it was.

If the image is too large it won't send; the maximum is 2000X2000px. I would suggest that you either resize it to 800x600px, 1024x768px or 1000x1000px.

I personally wouldn't put the blame squarely on the browser myself. While some browsers are faster than others (Google Chrome probably being the fastest), your internet speed will also impact on how long it will take to upload. Along with format and size (anything under 1mb should only take a matter of seconds to upload).

Which browser are you using? Sometimes that affects the load time I've noticed.

It wouldn't load.

Not being accepted as in the page wouldn't load? Or it was being deactivated? If the latter, was there a message with it explaining why it was deactivated?
