That's all very nice and all but it doesn't look too good and you can't give the pictures descriptions =(
However easy steps can be done to make it look better for a bit more advance users. (Seriously though, a 3 year old could do this)
1. This step requires you to know how to upload pictures to a uploading website such as
Photobucket,
Imageshack or others. It's easy to learn and the websites can explain better than I can
or want to.
2. Now that we have a url from the uploading site (I'll use http://img.photobucket.com/albums/v1...55618-Full.jpg ) we can add it. But wait, it's too large, we have to make it smaller and edit all these tags right? RIGHT?
Wrong. It's much easier than before FH now sizes down for you!
3. Now look at your Editing Bar (the one with Bold Italic Underline etc) for a button that looks like this: 
This is the image button, learn to love it. Obviously, click it now.
4. A box will open. It's asking for your URL remember?!
5. Paste that url in yo.
6. Your done, your picture is in. When you post the image will automatically resize and look beautiful like this:
The End for now.
There's a third way I'm still messing with for even advance users ( 6 year olds!)
