I know other software (I wont mention Jason) has this facility and gives the developer the option to store a graphic name or full path name, so its a little disappointing there isn't the option here.
But if that is your definitive answer, I appreciate your time and trouble replying to my question (as always, you guys are quick to respond and try to help).
Other software I'm using on the site I'm developing uses full path in db, which is why my question.
Many thanks
Mark
