Re-size image on file upload

Asked by xjdx in PHP Scripting Language, PHP and Databases

Tags:

I'm trying to add the ability to re-size pictures on upload, but can't figure out how, it's set at the minute to make sure the size of pictures is 629px x 481 px so that would need to come out of course, I've tried a few different things, but can't get it to work with a file upload, any help would be great!

I have attached the file I'm using to upload the images, it inserts them into a photogallery on my CMSStart Free Trial
