For most times, copying and pasting the image address/URL would be fine... in this case we get the point without seeing the pics <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' /> Unless, of course, it's a user error... then in that case seeing the pic would be good.
