Open "my computer" then look in "my pictures". Once you find your pictures posting them is easy... Just fill in your post like you normally would, but before you "submit reply" click on the "attach file: Browse..." icon. When you do that a window will come up and ask you to "choose file". Use the drop down menu to find "my pictures" (or wherever your picture is located on your computer), then select your picture and click open. Once this is done you can "submit reply"... hopefully if all went a planned, you should see your picture in your post.
