I can't say if it helps or not (you can get a higher exopsure if your collection is picked for a special subject, such as Valentine's Day or Christmas), but I like the fact that I can embed the collection in my own website or send a client the collection (not that I have ever done it).

Mark,

You can indeed set a discount price for the collection.

The difference in FP's collection is that you can embed it in your own website, showing as a table.  As far as I know, no other site lets you do that - all you get from them is a link that you can put in your website. 

I think it is much more effective if the buyer sees all the thumbs, and if he gets interested he will click on the image and is directed to FP.  A mere "click here to see my Valentine's images" is not attractive, or you would have to make your own table in your website with the thumbs.  FP's solution is much more practical, and if you add images to that collection your website's page will reflect it.
