You need to tell it where to put that converted image. It does not do it
"in place"

If you want a gui you could try Phatch - a batch image converter.

Its a python app with a .deb for ubuntu and instructions for other OS's.
I used the .deb on my Mepis (debian) system and Phatch works fine.

but _if_ you did want to convert "in place" then mogrify is the command to
use.

probably best just to forget this one. I have
phatch_0.2.0.bzr936-0ubuntu1~8.10~ppa1_all.deb installed

The latest phatch 0.2.1 has an added dependency - Blender of all things.
Any one who wants the debs & there is still the old version 1.6 That
works ok should see

Another possibility - a bash script I sometimes use bbips.sh

Its a good old menu driven front-end for imagemagick. I can't find the
download anymore, seem to remember it was a university site so I have
popped it onto rapidshare if anyone is brave enough to try it.

There are the individual components of the above, including the resize
script at:
