Are you a tired old Hector tonight SW? It's #19 but I'll give it you
Then you should put '20' by picture number 20 then dear
Why? There's already one #20 by picture number 20 - people might get confused if I did that.
It would be useful for people with 20/20 vision though .....
Is pic 20 supposed to be a small pic in top left and a lot of space ... or is it just my browser that shows that?
