How do I route images through ASP.NET routing?

Question

I\'d like to create a dynamic thumbnail resizer so that you can use the following URL to get a resized image:

http://server/images/image.jpg?width=320&height         


        

Answer 1

How about:

routes.MapRoute("Images",
        "/images/{filename}.jpg",
        new { controller = "Image", action = "Resize" });

That Should ensure that only URLs with .jpg as an extension get matched to that route and get routed appropriately.

Also remember you want to add your actions in order of most specific to least specific, with your default one being added last.

Of course, your action still needs to serve up the Image using a filecontentresult.
