Trouble with image colors

[solomon]

hi

I am having a similar problem. My bmp images are orginally black and white, and when viewed in image viewing or editing software (e.g. photoshop, paint, ifranview) they appear fine. However, when I attempt to display them in DirectRT, they appear blotchy in some parts of the image, and other colours (e.g. red and green) become visible. I have tried various monitor resolutions and resizing the images, but no success. Attached is one of the files.
