[php-list] Problems with code in one directory but not another

[whoisquilty]

The following code runs properly in the directory that is live, but in the one 
that is used as 
a staging area it treats the IF statement as if $image = 0, even though it 
doesn't. Any ideas 
why it would do this?

Thanks,

Jeremy
