Comment (by malu):

 Replying to [comment:13 sadrul]:
 > mlundblad: I believe it's important that if the client doesn't support
 custom smileys (e.g. an unpatched pidgin) then it will display the text
 for the received custom smiley, instead of completely removing it (which
 appears to be the current state, judging from the screenshot).

 Unfortunatly the current (unpatched) GtkIMHtml ignores <img> tags. So I
 haven't come up with a good way to let old clients to display just the
 shortcut. The best would have been if there was a defined capability that
 the client was supposed to present in case it supports images with
 embedded data. The plain-text body element of the message stanza on the
 other hand contains just the text of the smileys, so clients not knowing
 XHTML-IM extension will display the raw text.
