I've never paid for a PG (mainly due to the fact I can't get UKash to work) but personally I'd like to see someone fully dressed and undressing in each picture and finish off with a toy. That way it would show what we're getting and should cover most punters choice of picture.
Most of the WG in my hotlist have shots fully clothed, but that's just my thing.
I'd say in PG the more pics the better as you feel you'd get your money's worth.
I do wonder why they don't let the punter take the pics for the PG.
I'd be interested in taking pics for the PG only as it would mean I couldn't get caught with them but still have access.
Might ask on my next punt.
