I think that the more difficult part is to build everything for reading the bmp file from SD card. Then the road is downhill.

Infact, getting the pixel information from bmp file is rather simple (see for example http://en.wikipedia.org/wiki/bmp_file_format). I'm assuming you already have the VGA display driver, so you simply have to turn on the required image pixels.

I'm also assuming you are planning to use Nios or other processor to handle all the stuff.
