On the area below the signature, How do you bold, change the font, have a picture?

Under user options in Member Control Panel. Add an avatar...

Not an avatar under the name on the left screen edge but at the bottom of the screen. Like under the "ON-BOARD-DYNO". I want to put a picture of the guages. Like attach file? Thanks.

In your signiture area, type:

[img] www.put_pic_address_here[/img]

(But without the space I had to leave)

OK, but the picture is on my computer, not with a www. site. Will it go to browse?

Nope. Unfortunately, It must reside somewhere on the net. You should be able to go to like webshots or any one of a hundred picture posting sites, upload it there and call out the www.addy

you could always dump the picture into a thread
and then right click property copy the link and use it
