I love how the first two responses are details of how to make a fixed conversion and not a single speed (presumably a freewheel) - if its not in a list format we just won't read it!
Nick: The first wheel - a DMR kit should fit that wheel ok (or similar). That or break up a few old cassettes and space out the sprocket you choose. Read up on chainline.
The other wheel appears to have a threaded bit. It doesn't look like a track wheel. Probably an old style road bike wheel where you screwed the cassette on. You'd probably be best off buying a screw on BMX freewheel for this. You'll need a single speed chain though too (wider).
