I think the problem is in your logic - in English: "if file type is not jpeg OR file type is not png" always evaluates to true. If the file type is "jpeg", then it can't be "png", so the part after the OR matches. If the file type is "png" then it can't be "jpeg", so the first part matches.

Replace the || with && and you should get the block executing when the file type is not "jpeg" AND not "png".
