* Improve handling of wrong file extensions for image.
* - load_image: if the wrong mimetype gets passed, return error, instead of letting imagecreatefrom* fail
* - upload: detect wrong extensions, rename accordingly and add a warning
*
* Revision 1.5 2009/09/14 13:04:53 efy-arrin
* Included the ClassName in load_class() call with proper UpperCase
