Re: how do I (mclincoln)
Sure thing.
The first thing you have to do is host the picture (if it is one of yours) on a picture hosting website.
Try
http://imageshack.us. They are the simplest as they give you the IMG tags already and all you have to do is cut and paste the link.
I'll do a demo of what it would look like below, except I'll use the brackets ( and ) instead of [ and ] to fool the computer.

Some websites will allow you to link pictures from them. Right click on the picture and look at the properties. Copy the URL for the picture and put it in between the IMG tags (that is the button on the right hand side of the left bar above where you type a reply) then hit the preview button to make sure it doesn't come up with a red X.
Hope this all makes sense to you. If you're not sure let me know and I'll try to explain better.
