Once logged in, go to advanced button below text window. This will take you to second page where you will see a bunch of options above the window for font etc... in the one window, there are symbols for adding link, insert photos or insert video. Select insert image. This will give you an option of picking from a website or browse your computer. Browse to the pictures and select them, (probably best to do one at a time)when selected press upload button. Unless they are really big, this should do the trick. You can verify by hitting the preview button at the bottom of the window before hitting the submit reply button to make your post.
Looking forward to seeing your beauty even if you get the pictures upside down the first try. :thumbsup
