Yeah, yeah... laugh at the old guy, he's a bit slow . Actually, did know all that, i just worded 'big image file at around 1.6GiB needed the 3GB switch for FIU' a bit badly. Because i initially thought that BB was saying it had a large tile like GB Discoverer, but if i'd read all the thread (like i keep telling others they should have done) i wouldn't have made that mistake.

Thanks for taking the time to explain Caty. I need to go and sulk now!
