Toolbar images not showing

[Strings]

Hello!

I was developing on a 24-bit True Color graphics mode on Win2K.
The toolbar images were of 8-bit indexed colors. The images displayed as expected.
But when I changed Win2K's graphics mode to 8-bit 256 colors, the toolbar is there but no images for the buttons showed!

I'd like the images to show in all color modes.
How can I do that?

Here's the routine that displayed the toolbar. If there's a better way to do this, please help. Thanks in advance!
