I set up password protected pages for my clients to proof their images. Once they are proofed I would like the ability for them to just hit one link which would start to download a folder containing all their images. I don't need an eCommerce solution for that right now as I'm not requiring payment. So do I need a plugin for that? If not I can use FTP to upload the image folders but need to know how to create a link that will start a download.
