The first step is to look for the picture you want on the web then left click the picture and push "save as". Once done it should download it. When you are done downloading it we like to use
http://www.tinypic.com and upload the file. Now you can do this on our site also but you will only get a link. The link at tinypic is custom to forums and makes the picture show up. If you want the picture to show up in the forum then you copy the
IMG Code for Forums & Message Boards only link and paste in the forum.
