Thank you. But I still can't do what I want... I want to have bmp picture in my dialog, and after reading your post, I tried this
icon , 123, -10 -25 70 100, "blabla.bmp", noborder
but no luck. Do I have to specify the exact (actual) picture width and height or I can use 70 x 100 if I know that my picture will fit into this?
