Wildbuck still on the run ... with another problem.

I want to assign icons to my interface ( ex : letter icon appears on a
e-mail link mouse over or mouse down ). I've prepared my icons ...
they're pretty, in a 32 x 32 pixel format with in the file both 256 and
16 colors.

It works but they appear in black & white ...

Could someone help me once again on this new problem ?

Cheers
