I must say I'm impressed with the number of replies! In fact, you could say I'm snowed under!
I'm trying the suggestions, some more suitable than others.
What I'm trying to do is to 'doctor' a still photo taken during during the summer months to make it 'winterised' or 'Christmassy' to send as a Christmas card to friends.
The BoltBait plug in won't load onto my PC (Windows Vista) as the screens are very different to those shown on the demo.
Still, "If at first you don't succeed...................."
Thank you all for your replies, they are a big help and I'm sure I'll get there.
