Combining scripts problem

G'day again
I got the gallery to work when I was using small images; but I want to resize larger images & use them instead.
I had a resize script that works on a single image at a time...but when I put it in to the gallery script doesnt work.
I'm not getting any errors...just no results.

Do I have to do it differently to get the image info from more than 1 result?
The resize starts at line 206.
Can someone please point out what I'm doing wrong here?

1) What has this to do with PEAR? This belongs in PHP Coding.
2) How are we to know whick line is 206 without sitting here counting them.
3) Please put the code in the forums PHP tags.
4) What have you done for debugging to find out what is wrong? Do you at least have error_reporting set to E_ALL and all error supressions (@) removed? We need a more specific information for what is going wrong.
