This is a gallery system that works with flat files, it doesn't use mysql and its free. I'm trying to decide if it drop this or not, because so far everything i got was lost time. In resume, do you think anyone in the world will ever be interested in something like this? http://animagallery.co.cc/
That means you have to submit each image by hand? I know photo sites like Photobucket have seen great success - so I'm sure there's still a market.
You can submit images by hand (standalone http), but it will also automatically show images already present in your server folders or new images that you upload by ftp/cpanel. Even if there's a market for it doesn't mean you'll ever reach lol... Also if a product has enough exposure it will create it's own market even if there wasn't any room at the beginning. The problem is getting that exposure <.<
