Small PHP Task - Image upload via PHP to FTP, Zen Cart Mod.

I have a few small tasks to be completed by an experienced PHP programmer. 1. Fix the current image resizing code. Scale the image and set a maximum width an height instead of automatically setting image to set width and height. 2. Create an image upload via PHP to FTP to upload additional images for each product. 3. Display the additional images on the zen cart product description page and enable larger view using lightbox. 4. Enable lightbox for the main product image enlarge in zencart The php to ftp script already exists for the product image uploads. I need you to copy and slightly modify for the additional images and store in a different table.
