I am working on a image upload form.

I want to use more than 1 upload field and my code allows for all to work fine.

My problem is that only 2 images gets uploaded even if there is more than 2 fields...

This code allow for different image extensions and create 3 re-sized images of each uploaded image

I hard coded the amount of fields in my script to be set as 4 upload fields with 

$pictot = 4;

Please have a look at my script and tell me what I am ding wrong as only 2 image sets are uploaded even if I use all 4 fields... AT this stage only one image set display and will sort out the rest as soon as I can fix the loop....

 

Thanks

 

<?php
