[font=arial][size=14pt]Hi,
I am pretty new to PHP. I am working on a Thumbnail Generator script. It reads the images in a dir selected by the user, then determines there file type. It then makes a thumbs dir within the photo dir to place the thumbnails in if one isnt already created. It then should create a thumbnail of each image with a size based on the user input. Unfortunately it only works with some images. Will this work on all image sizes? Will different aspect ratios throw this off? Do I need to use jquery or ajax to give it time to process? I am unsure of what is causing the issue.[/size][/font]
HTML that calls the PHP code (used on Foundation Framework)

Any help would be greatly appreciated. Thanks again!
