You can usually just change the name of the file extension also.  Instead of having Mustang.bmp simply change the name to Mustang.jpg  If you cannot see the file extensions, open any folder, go to tools, and select folder options.  Once there look under 'Hidden Files' and uncheck 'Hide Extensions for known objects'  Now you can just change the name to whatever.  This doesn't always work for every type, and it's certainly not the norm.
