If you have imagemagick installed, you can cook a short bash script utilising 
'mogrify', like so (adjust seasoning to your liking):

for img in *.jpg; do echo $img; mogrify -resize 640x480 $img; done

Run 'mogrify -help' for more options. Other useful program from imagemagick 
that I use quite often is 'convert'.

Ciao,
