I'm using the "Gallery Thingie" script to run a simple gallery. The idmin area lets you reorder the images by changing the "id" number. I get a confirmation message "Thumbnail updated. Thumbnail deleted. Image edited." Everything is reordered, and the thumbnail is deleted, but the thumbnail is not recreated. If you go back and click "update thumbnail" again, the thumb IS recreated. How can I get a new thumb created when the id is changed? ($newid)

I don't know anything at all about php, so if you can help, please explain the obvious. Thanks!

Here are the snippets that seem relevant:

PHP Code:
//    EDIT IMAGE
