DISABLE WINDOWS PICTURE AND FAX VIEWER.
By default, Windows XP opens all picture files (gif,jpg,...) with the included Windows Picture and Fax Viewer no matter what other picture viewers you have installed. To disable the Windows Picture and Fax Viewer, unregister shimgvw.dll. This can be done from command prompt: regsvr32 /u shimgvw.dll
