Diagram

That's a smart diagram EtU. Where did you get it from? It's exactly how I felt.

Apologies for the re-issue of my article in a strange format( a result of experimenting). I had a pal here this morning and we were looking at the photo enlargement problem. As you can see it does enlarge but beyond the screen capacity. However I note the same is true of NLN's photos. Well certainly on my screen anyway which has a resolution of 1280 x 1024.
