However at one version of adium this feature broke and no one seemed to notice or didn't care and now the way to do it is to right click the image, select open image in new window then drag the url from the toolbar to the adium window. If a user just drags the image they get the green + pill but adium does nothing.
Please if possible bring this feature back, it may seem small and insignificant to some people but I seriously do this like 50 times a day and MSN is driving me mad with its random crashes and now adium losing features i grew to love
Thats what macos is all about to me when you want to do something you think "how would it work in a perfect world?" try it and thats the way to achieve something
