Are the images user-specific?

If not, why not serve them out of a directory which does not permit the
index to be shown/browsed?

If yes, you can do the same by mangling the image file names with some user
id kind of string.

Non-authenticated users will not know that string since your webapp won't
render it to them.

You can achieve the above with an easy-handler I think, and even just use
nginx and get better caching control.

You can also use a dispatch route, but I don't quite see the need for it
yet, since you're only serving up files..
