note 44018 deleted from function.imagecopyresampled by tomsommer

Note Submitter: nateritter@email.com ---- I didn't see it mentioned, but the extension upper/lower case does make a difference. I have only tested this with jpgs but if the extension of the file is in upper case or mixed case, the resize won't work. Additionally imagecopyresized() won't work like that either. The extensions should be lower case for the resize to work. Otherwise you get a "not a valid Image resource" error.
