and where do you get them from
davidjt
There are a load available in the Forum Profile section of your Profile Settings, or you can do as Neil says, and find/resize use your own image, and...
...whilst, I can understand how they may help with quick recognition of established (mis)users...
Why?
I personally find them useful when scanning down a long post.....I can spot the people to ignore
...they are apparently an optional feature, not a compulsary one...
Why ?.
As people tend to change the pictures anyway.
...so I still don't really know what they are about?!
