Combine Multiple Images to 1 - Image Creator

I need a script made that works like this one: [login to view URL] Changes/Additions: -When you click Add Icons it opens up a selection of his icons. We have our own icons we want to use so we need a mass uploader to upload our thousands of icons, or just have it so it pull the icons from a folder so we can just upload them there. -Need an option to use images from URLs (if possible). -Option where you can remove border alltogether, if 0 width is chosen it will show a dotted line just for the preview outline. -Option to chose height/width of boxes. -Option to check a button to automatically resize images to fit within boxes. -Ability to stretch and shrink each image. I need this asap. A different color picker will need to be used also. If you have any questions please ask.
