Thought I'd share this article. Quite useful for anyone thinking of updating their profile - me included. 

A lot of commonsense here but some of it is counter-intuitive and there is a great link to a helpful site which will review your pics - only for the brave!

Not a great start to the day if you get 100% feedback that all your pics suck!! 

That's when you forget the morning coffee and get yourself a stiff whiskey.
