I can't give you a straight answer.
 
The only thing I can say is that the RTM seems to handle graphics images differently than they could. Try making the logo into a .GIF or .TIF, and/or changing the original size/resolution so that it matches what's on the form.
 
In other words, just like any aspect of RTM editing, you may have to spend some time figuring it out yourself since there's no manual for it...

After much playing around I got it to look pretty good.  I tried several different resolution sizes on the original along with using the stretch option.
 
Thanks
