Joyce,

No problem. You could do as above (saving as a script), but I usually just 
type one-liners like that in the shell directly. I had done that often enough 
to remember the syntax :-)

One thing I forgot is to use quotes, just in case the files have spaces in 
their names, like this:

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

Might want to check the website, I'm sure they have documentation. I only use 
mogrify and convert, other than that I'm not too familiar with imagemagick.

Hope that answers your question.

Ciao,
Ronny
