See copyrightbox.pdf, but the short version is

\copyrightbox[<placement>]{<image>}{<text>}

where <placement> is either
 r    (Default) Text to the right of the image
 l    Text to the left of the image
 b    Text below the image

which puts <text> positioned according to <placement> near <image>. E.g.

\copyrightbox[l]
		{\includegraphics[scale=0.5]{coin}}
		{Image put in the public domain by the U.S. Mint.}
