A login box will appear and you will put in the username and password you just registered. Once logged in this will open up the Cisco Feature Navigtor. I find the "Compare Releases" the best when wanting to look at all the features of an IOS image.
To help you along on the search, the two images you have are:
c-l is the Remote Access Server feature set
is-l is the IP Plus feature set
Hope this helps.
c2500-is-l.123-12.bin
c2500-c-l.123-16.bin
If both have filenames like above I would choose the is-l version to put on the router.
