You can't post pics off your hard-drive. Trust me, I was trying to do the same thing last week. The guys told me something about a test page on the web where you can bring pics from your hard drive and post them there then copy and paste them here.(something like that)

To post a picture, check the box that says 'I want to preview my post and/or attach a file'. You will see this at the bottom of the page when you are entering your post. When you click the 'continue' button you will be taken to another screen where you can select the picture you want to attach. Now, click the 'browse' button and select you picture from you PC. The name of the file will now be in the heading or your post. Other users can 'double click' on the name to see the picture.
To include the picture in the text of you post, just type (image)url of picture(/image), replacing the ( ) with [ ]. To get the url of the picture, 'right click' on the name and select 'copy link'. Now 'paste' the link between the image tags.
