Graphics: vector or bitmapped? The solutions suggested by others  
(ImageMagick, GraphicConverter, TIFFany3) are really fine for  
bitmapped images, but less suitable for vector (line) art.

Changing some meta comment in the (eps) header is easy enough with  
sed, but adding some string to the lower left corner of the (eps)  
figure shouldn't be too hard. If the figures are in pdf format, I  
think pdftk has some helpful options: http://www.pdfhacks.com/pdftk/.  
One of the options allow you to place a background watermark on a pdf.
