To post pics, you can use the Attach Files option that is underneath the window where you type responses. This will give people a link to click on in order to view the picture. To post a pic in the response (immediately viewable), you have to upload it to an online place such as www.ImageShack.us. Then you cut and paste the http address for the picture into your post and it shows up!
Jimbob, you may want to resize those as they are really big. The scrolling from side to side is annoying, and it hurts my eyes. There's an option for that on ImageShack
