I'm looking for a [XMPP][1] or [LAN messenger][2] where users can paste images from the clipboard and the pasted images are directly shown in the chat window (or a separate window) to the recipient without the need to explicitly download the image or click a link. Multi-OS support would be a plus but mostly for Windows.
