/*************************************************************\
* Image resizer, version 2.2 - August01,2003 *
* Returns true on success, false if there are errors *
* If destination file is specified, resized picture will be *
* saved with the specified name. Else, it is shown to browser *
* Version 2: Now scales both up and down, still preserving *
* aspect ratio, and it accepts not only jpeg, but *
* also png and possibly bmp *
* Version 2.1: Genereal optimization and bugfixing. *
* No longer requires GD-lib to be >=2.0.1 *
* Version 2.2: Removed use of image_type_to_mime_type() *
* Added the array $mimes instead *
