Shopping cart for large number of photos

I am looking for Shopping cart software suitable for large number of photos.

I require the facility to upload images in bulk (hundreds at once), creating a thumbnail image for each one. I don't want to specify a description etc for the photos, the photos need to be uploaded into a selected category, the filename (a number) should be the id and the price should be defaulted from a standard price by size. I also want to be able to create pricing packages, eg: 2 photos at a particular size + 1 photo of another size is less than the price of the individual photos.

Do I need to write something to suit this purpose or is there something already around?

Sounds like 2 different applications to me; one shopping cart and one file transfer app. You might look into Irfanview. It's a freebie that will create your numbered thumbnails (I guess that makes 3 apps). I don't know if the latest version has FTP capabilities, but that's easily handled, too. I'd be very interested if you can find an app that does all you are asking for in one package. Good luck.
