a market that has a lot of users who will use your product
Photo sharing fits the bill just right. Facebook has shown you can also make money off it.
Ecommerce is always a great market, but it's too vague because it's just commerce through a new medium. I'd prefer and love to read blog posts discussing specific ideas. Take that as reader feedback :-P
To be honest I didn't want to name specific markets as I didn't want to create too much interest in areas where friends of mine are working. I didnt want to add attention and make it more crowded. :)

Did you see this Mixergy interview with the founder of Gemvara? http://mixergy.com/matt-lauzon-gemvara-interview/
It is one of the most innovative ideas I've come across recently, and apparently executed very well too.
