Automatically re-size graphics and brand ?

[Darren Wyn Rees]

I wonder if the following is possible with Ubuntu.  I'm currently doing
it laboriously with proprietory software :

Process a collection of photographs in a directory ...
* Automatically re-size the photographs to a pre-set size
* Add a 'stamp' or some sort of copyright image on the bottom
  right corner of the image

Suggestions on what software to look at appreciated.

Darren
