Snake: thanks for the links and heads up on the commands. Rich, thanks for moer info and some psuedo. I've used Image Magick before, funnily I was speaking to someone the other day and they reckon it's a bit on the slow side compared to other tools but not knowing too much I didn't comment. Saying that, it's free so great! I'd be interested to hear what you think?... Thanks again and I'll be back... Cheers, Nick p.s. Is there not a lot of activity on this group?
