I keep getting this message from rumpus Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, email@example.com and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log.
Where are you uploading the images to - if its into cgi-bin on the ccgi server or a sub-directory of it then you cannot use that folder for normal files, it is designed for shell and perl scripts. That error can also be caused by a bad or mis-configured script / php file. I would check the configuration and ensure the paths are correct.
