DevIL is a good library if u want to convert or show or do anything with your images
http://openil.sourceforge.net/
I used it for my last visual c++ project

Thanks to both sunnycoder and dkloeck,

So sorry, maybe I not specific  well what I want.

I am more concern with the format of a 16bits grayscale image.

For example, a 24bits RGB Image may consist of:
   1. Bitmap file header.
   2. Bitmap info header.
   3. No pallete.
   4. Bitmap data (which every 3 bytes represent a pixel. Each byte for a channel - RGB)

For a 8bits grayscale image in bitmap format, I know it consist of:
   1. Bitmap file header.
   2. Bitmap info header.
   3. A color pallete with 256 entries.
   4. Bitmap data (each for a pixel and it is the index to the color table / pallete).

I wish to know how a 16bits grayscale image is represented in a bitmap / I wish to know similar information (as in the above examples) about a 16bits grayscale image.

Thanks and hope somebody can help. Thank you.
