It's really good that you reported ithe server error, zazzle tech need to know about the errors.
A couple of suggestions---
To eliminate the possibly that the image might be the problem, try to resave one of your images again on your computer, it may have saved wrong when you first saved it. Upload the newly saved image, see if that works.
If not---
From an earlier post I replied to about this same issue---
Try this—-
clear your browser cache, history,cookies etc.
Close your browser.
Log out of zazzle.
Restart your computer.
Login to zazzle, try again to upload your image.
Most likely if your image was not the problem, and clearing the cache doesn't resolve the problem, your upload attempts won’t change anything till the server stops erroring out on you.
And, most probably your server error has to do with the server having issues, not necessarily an issue with what you are attempting to upload. (sometimes the server error type wlll show,so you can google it, like server error xxx, but yours doesn't show the type of error.)
Lastly, it may be a matter of timing. The server error could resolve itself while you are trying to resolve its problem.
