334184 Magento custom extension

I need a custom extension programmed for a Magento cart. The store owner is selling photos on the website as downloadable goods. He would like to be able to add bulk photos at once (over 100 at once in some cases) instead of adding them one by one (which is far too time consuming). The store owner would upload a folder of the full resolution images to the server via FTP. Then he would be able to select this folder in the Magento extension and it would create a downloadable product out of each image file, and would also create a smaller watermarked thumbnail. All photos will cost the same amount, so the extension only needs to allow one price to be set.
