Find Delta Shower Fixture, Chrome and other Faucets at Aubuchon Hardware (http://plumbing.hardwarestore.com/51-287-tub-and-shower-single-handle/delta-shower-fixture-636474.aspx)

I am tiling my tub and I need to remove a one handle shower knob that is very similar to this link. I can't figure out how to get the handle off. I also don't know how to attach a picture of the real handle which would probably help explain my problem. If anyone knows I would greatly appreciate the help. Thanks.

Look under the handle for a set screw, probably an allen type but could be a slotted screwdriver type.
