If you are looking for a picture of the OEM remotes that come with a particular device, for the most part you have to go the manufacturer's web site and hope they put a picture up on the page for that product. Sometimes they provide links to user manuals through their support section; those usually have a picture or diagram of the remote.
But I still recommend remotecentral.com. The idea is that you just get one of the better true universals listed there whose layout you like (I along with many others like the Home Theater Master MX-500). This one remote will completely replace the functionality of all your other remotes, and from then on it doesn't matter at all what the remote that comes with your equipment looks like, just that it supports the commands you want (e.g. on a TV w/ many inputs it's nice to have direct source selection on the OEM remote to teach your universal).
