PHP Image upload fails FTP connection - php

Question

I'm having some trouble debugging an old website. The original programmer is long out of touch, and I can't seem to find the error. The problem appears to be that when the user uploads an image, it never makes it to the ftp directory. The database values for description, file name, etc are made. Credentials are known good and tested.
I've done some looking and found a few scripts that do much the same thing; and it appears the PHP functions are all still valid (searched them at php.net). So I'm at a bit of a loss.
This script just stopped working two months ago. There was some DNS trouble with the server, but it was resolved and all seems well. Not sure if it's related.
If anyone can spot the problem I'd greatly appreciate it!
