问题
I need to create a photo gallery service that is managed by users. I've done this a million times using just Asp.net but I was wondering if there are any special considerations that I need to make when using Asp.net MVC.
Basically, I will be storing the actual images on the filesystem and storing the locations in a database linking the images to a specific user. The images in a user's gallery should NOT be accessible by anyone except registered users. Meaning, I need to somehow prevent users from sharing the URL of an image from a gallery with someone who is not a user of the site.
In the past I did this using some generic handlers which authenticated that the request is allowed to access the image resource. Can I use the same pattern but using Controllers instead? I was thinking of perhaps creating a Photo Controller and just a simple Get action. Would this require that I have a View just for displaying an Image?
Am I on the right track or are there better ways of doing this? (Besides storing images in the DB)

This link explains how to create a custom ImageResult class. I was able to do exactly what I needed following it

It's not a complete answer but I'd look at using a route that restricts access to the actual files themselves and then possibly use authentication of the action that gets an image.
