This is usually an indication the web user (IIS_USR for example) has no rights to save any data to the folder where you are saving the bitmap on the webserver.

I had similar problems before. Check the access rights on the server for that folder. Start out by giving everyone full access to that folder (just to make sure that is the problem) then narrow it down again so only the required user has access.
