Is there a e-commerce photo niche that needs filled?

My question is this, is there an niche in the online photo market for selling content in someway that needs to be filled?

In my day job I specialize in developing services that allow video producers to easily sell their own content, from their own website. For example they simply upload a video, add a buy link on their website, and my service handles the commerce/delivery portion of this. This happens with and without DRM if they wish.

As I'm sure you know, a person could easily add a paypal link to their website to sell photos, but how you restrict access to only the person who paid for it is tricky for non-techies (and even some techies).

This niche for Video has been pretty profitable so far, and I have considered branching into a photo solution, but is there actually a need for a photo service of some sort is the question I'm asking.

I was thinking maybe people need to sell 15Meg RAWS or something, but honestly I have no clue what the indepedant photographers would like to have as a service.

Anyhow, thanks for any input.

More questions to add to your question, so consider this a <bump>: Password protect downloading it. It would probably have to be shown in flash, but wouldn't that end up in their cache, too?

Looked at eBay recently? There's a market for everything!

For the protection of downloaded images what I meant is lets say you show a thumbnail/brandmarked version of an image on your site, with a Buy option. If they click the Buy button they pay through paypal, and then need to download the file. The downloading the file part (and not having a url they can just post on a message board) is what's tricky for most people. This is a problem we've solved for video downloads.

The way my business worked for Videos is we knew there was a need for this, but instead of just saying we had a video sales system, we targeted specific use cases, such as building a method for easily selling Instructional Videos, or securely distributing Corporate Announcements.

I'm looking to hear if their is an unaddressed particular niche in the photo selling space that people feel is needed (or improved upon). But maybe the bases are all covered.

The first thing people try is password protection, but then the problem is how do you put a different password on each file and not just the directory. Then they do password protected zip files, each using a different password. At the end of the day they often end up manually ftp'ing the images they sold to a website and giving the user the url after each sale, which is not a very hands off process.
