Multi-Image upload for classifieds site

I'm looking for a mod to allow users to upload multiple images to a classifieds site. The script is XZeroscripts so you will need to know a little about how it functions. Right now the config file setting allows admin to set the number of images a poster is allowed to upload but when the poster uploads they have to do each one individually. It needs to be changed so the poster can select all the images at one time and post all together. Similar to how the multi-image demo works here <[login to view URL]> The mod will still need to look at the config file to see what the max allowed image upload is. I need the mod to be a little fancier than the demo above and maybe show a thumbnail next to each file that is about to be uploaded. Also give the poster the ability to delete one or more images before finally submitting. I will suply a generic XZero site for you to work on with FTP details. The code MUST BE UNIQUE (No copying) as I need to be able to sell this mod as my own without worying about copyrights. Make it look fancy so it's easy to sell. Thanks
