Bug with Image_lib.php - images with new_image set with full path produce bad dest path

This is mostly invalid. I have found the problem in my case, my new filenames did not include the file extensions (they are generated from the original file name plus a timestamp, and as a left-over from an old script, did not have the extensions reattached to the name). Image_lib.php was assuming the value of new_image was a directory, despite the lack of a trailing slash.
