Hi Damien,

It looks like #httpShowGif: displays the image without needing anything
further.  It then returns a reference to the HTTPSocket class.  This is by
convention: if a Squeak method doesn't return anything specific, it returns
the receiver.

HTTPSocket class doesn't implement #display, so that's what is causing the
error - but in this case, there's no need to send another message, since
#httpShowGif: does the showing by itself.

Hope this helps,
