Thanks Ed - I can't remember the model - cheap, cheerful, slightly smaller than a house brick, with a waterproof plastic box...

I've never been one to spend any kind of money on a camera - most of my electronic gadgets have a fairly short life-expectancy...
My latest is an Olympus U770 SW that I got for my Namibia trip last year. It's small, waterproof and has survived everything thrown at it so far (including a week of living rough in a desert), but I haven't yet had the chance to take it to any kind of depth.
As for the photoshop thing, I got CS3 a few months ago, but haven't had the time to sit down and figure out what's what with it just yet - it's on my list for the summer!
