This is quite easy to do in Gimp using manual methods, but if you have
more than a few to do, then I use Imagemagick
http://www.imagemagick.org/ and create a script that does this.
Using the Imagemagick methods and other scripting techniques (perhaps
Perl with the Imagemagick Perl module) one can, for example, vary the
size of the watermark based on the size of the underlying image.
I used to use these Imagemagick/scripting techniques to create JPEGs (in
four different sizes of each, with the four resulting sizes constrained
by the original size based on some very complex logic) and add watermark
to _tens of thousands_ of original TIFF files (leaving the TIFF files
unchanged, unwatermarked so that they are available to me for other uses).
It is very powerful stuff, but it can take a bit of work to learn.
