Answer 1

I would use ImageMagick which is installed on most Linux distros, and can be installed on OS X using homebrew and can also be downloaded for Windows from here.

Say you have an original image like this:

and you have a watermark saved in a file called watermark.png you can do this:

convert image.jpg -gravity southeast watermark.png -composite result.jpg

which wil give you this:

As regards batching the commands, you don't say what OS you are using, but if it is OSX, you would do something like this in Terminal:

mkdir watermarked
for f in *.jpg; do convert "$f" -gravity southeast watermark.png -composite watermarked/"$f"; done

If you are on Windows, you will need to use the mad Windows FOR loop syntax, which is something like

md watermarked
FOR %A IN (*.jpg) DO convert %A -gravity southeast watermark.png -composite watermarked/%A
