We have 1 "real" GPS between two geocachers/waymarkers and a GPS enabled blackberry, so taking a picture of the GPS isn't always feasible. We have over 500 visits and not one picture of a GPS in the shot and we've never had a log deleted (I assume the system notifies you like GC.com). As long as you put some thought into your log, maybe a complete sentence or two (not just TFTW!), I don't think you'll have a problem about not having the GPS in the picture.
