Image without its background color

Hi all,

Does anyone know how to display a bitmap (or any kind of picture) without its
background. In other words, I'd like something like we may see on the Web with
Gif89a pictures. For the moment I use the TSpeedButton, but am not really happy
with the result (though I do not have the background). Indeed, since it's a
button, then I need to disable it (and therefore to have 2 pics instead of
one). But the most annoying is that it's a button, and that I do not want a
button but just a picture. Any help is welcome.

        Regards, Alan.
