Perhaps it's only me, but I am just plainly unable to get the image upload working on 2.5.1 installed on a server running php suexec. I am able to get the dialogue box to select the file I want, but once I proceed, I get a "crunching" message and it finishes with an "http error", and the file is not uploaded/processed at all.
I know it works because the exact same site, installed on xampp gives me no problem whatsoever.
Any idea how I can resolve this? It's pretty major if I can't use the native image upload/processing.
