Hi Damien,

I've tried this code :

(HTTPSocket httpShowGif: 'http://www.google.fr/intl/fr_fr/images/logo.gif') display

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, Ben Schroeder

apparently this changed since 3.0. so you do not need to send display anymore. In 3.6 there was a big rewrite of the network packages.

It displays the logo but a bug too :
