Ahhh excellent! Thanks for that! I'm not sure how i missed the newbie subforum! Either way I've now got so many settings it'll take me a while to get used to them!
I used a 16mb card as a tester and a single 8mp RAW image fills it, to the point of causing the card reader to not read it again lol?! Oh well! I'll get the 4 gig card up and running tomorrow!
Thanks for the pointers, sorry for the dumb-[admin: avoid swearing please]-didnt-look-far-enough newbie post!
