I'm trying to use this image from my wife's World of Warcraft game for her computer but when it gets turned into bmp it turns out looking like this.

It has these green purple and white dots on the flag image. I've tries several different formats with several results. All of which suck.

I haven't seen any topics dealing with this subject except for one from 2004 that said
"Make the whole page up layer by layer in something like Adobe Photoshop or better still Dreamwaever Fireworks.... render the image pixel by pixel so that the whole page is correct for colour loading to boot"
Any suggestions for reducing the color to bmp that won't have these dots?
