Dattong, It is very easy, this comming from someone that up until 2 days ago could not for the life of me figure out how to do it.
Here's how to do it......fill in your message, go down to the bottom of the page, hit browse, browse through the photos you have on you computer, when you find what you want , open it and hit the post reply. As long as it's not to big and is JPG form it should load with no problem.... Good Luck!
Thanks again to everyone that has helped me....Lisa
