Error Uploading Images

I keep getting this error message. I was uploading images just fine yesterday and now I get this message that has me dead in my tracks. I even tried uploading a copy of an image I had uploaded successfully yesterday and I still get the same message. I've tried different browsers and I still get the same message.

OOPS... SOMETHING IS NOT RIGHT
