Importing bitmaps? I dunno about this palette stuff...

I am importing a bitmap, and I don't understand all this palette stuff.

My file is NOT 256 color, it is 32 bit. How would I get it into my program? I've set the color mode, but when I try to blit it to the screen, I get a 256 color image.

Make sure you call set_color_depth() and set_gfx_mode() before loading your image file.

I did.

Post code. And the image, to make sure.

You need to call set_color_depth()before set_gfx_mode();
