This site is in German but you just have to click on the pic you want (in the middle of the page) and copy and paste the IMG code in reply box. The pics at the top and bottom are the menu pics, click on those and it will take you to a cornucopia of pics.

Here you have to right click on pic that you want, then click on Properties and then copy and paste that URL into your message but put the [ img ] [ /img ]around said URL, again no spaces when you do it.
