Thanks, Stoker! I tried a few different ways (even followed the directions) till I got it fairly right.
I open up the photo, and go straight away to "edit" then the "define brush" option turns up (sometimes). I tried to make the selection for the bit I wanted to use as a brush, and the "define brush" did not turn up, only the "define pattern".
I think I have it down now, though. I think if I make the elipse or rectancular section of the photo in another graphics programme, then bring it up in PS, it will work.
