There are a couple ways. If you have the picture posted on a picture hosting site, like imagestation, photoisland, etc, you can type the picture' s address in between and check on " click to upload" (down at the bottom of this window).
Or, if you have the picture saved on a disc, check " imbed picture in post" , and click on " click to upload" . A box will pop up. Click " browse" , select the picture you want from your disc, and hopefully it will be accepted. It will need to be 30kb or less to load from the disc. If it is larger, you' ll need to alter it, which is mostly greek to me.

Hope some of this helps!
