Two ways: First is to upload it from a hosting site like photobucket. Click on the little image that looks like a mountain range. It's to the right of the globe icon. Paste the URL of the image into that.
Second is to upload directly from your computer. Click on Go Advanced down under the message box. Then click on the paper clip icon at the top of the message box. A new window will open. Click on Choose File, then find the file you want and click on it. Click on upload. Repeat until you've uploaded all your pics, then close the window. When you post, the images will appear. If you want to manually insert them, click on the paper clip icon again and select the file name.
Does this help you?
EDIT: Olympia, haha. Glad I'm not the only one. :D
