its not that simple.

You will need some sort of ram/rom to hold the image. And a VGA controller to display it. Its not a simple conversion.

Use Irfanview software.

Select open in Hex mode --> the bitmap file then opens in Hex mode where you can see the exact structure of the file including the Headerfile, Infoheader, pixel (Raster) data, etc. This would give you a lot of understanding of bitmaps which will help you display the image.
