You can copy the old ones? Or do you mean, just get the [text] representation? That could be because there's extra information added to the page for the board-integrated smileys while the others are just external images.
Nope. That happened the first time (with Superman smilie), but after that I can copy the image to WORD but not a moving image, if I try to copy it to e-mail or here my computer tells me that there's nothing to "paste".
