As a temporary solution you can link your FB photos on here as well, just open the pic on FB, right-click, then click Properties, which should show you the URL of the JPG file - then use IMG tags here (or the picture/Mona Lisa icon visible at the top left above the smilies when posting).
Some browsers do not have the Properties option when right-clicking the image, but give you a possibility to copy the image URL with one click. Just right-click the image and look at the options the browser gives you. Not that difficult with a bit of practice.
By saying temporary at the beginning I mean that FB photos keep changing their addresses, so with time photos linked like this gradually disappear...
