You can use a variety of methods to upload images to show them, but Facebook is not really one of them for a public message board, as one needs to be registered at Facebook to even look at that screenshot.
And I am not, though I am still in the majority, but maybe not with the online population.
Anyway, you can use www.tinypic.com or www.flickr.com to link to uploaded images or you can even attach an image to your post via the
button, which is located in the first of the two rows above the text entry field you might use if you ever post again.
