Options Tab:  If your pic is 640 KB or less, this will allow you to point at the pic on your computer and add it to your post.  This method limits you to one pic per post.  At the top of the post you will see several tabs:  Compose, Options, Related, Preview.  Click on the Options tab and click the "Add/Update" button under "File attachment".  The rest should be obvious.  Don't worry that you don't see your pic in the preview.  By the way, if your pic is larger than 640 KB, you can use Microsoft Office Picture Manager to resize it.  Click Picture then Resize.  If you don't have this software, there are a multitude of other programs that do the same thing.

Tree Icon:  On the Compose tab, there are a bunch of icons.  One looks like a tree.  If you mouse over that icon it says "Insert/Edit Image".  You can use this icon for pics that are larger than 640 KB or if you want more than one pic on a post.  It takes a little more work.  You need to supply a URL for the pic(s).  I add pics to my gallery, copy the link of the full resolution version of the pic, and paste that URL into the form that comes up when you click the tree icon.  You will want to resize the pic if it goes off the page.  I have heard that your post will have to be approved if you have more than four pics in a post, so you probably want to limit the pics to four per post."
