Bitmap Image posted with weird colors

[peterjuras]

When a stream with the content type: "image/bmp" is posted to the facebook wall the colors get messed up. Is this a bug on your or on facebooks side?

Example:
When an image is selected in internet explorer and shared the Bitmap shared object is of "image/bmp" type and can then be uploaded to facebook.

bmp isn't a common format at all. use png or jpeg.
