First off, since you like the theme so much, mack sure youi give Flynn a donation so he'll keep maintaining it!
that said, I did some work with nextgen gallery in the header (see http://forum.bytesforall.com/showthread.php?t=1197
) and it worked, my only problem is I could never figure out how to round the corners of the omage. I wanted the top cornors to be rounded. so you can try that out.
