Thanks, I used:
for i in *.jpg; do convert -resize 800x600 -quality 75 $i tn-$i; done
The really bizarre part was that I thought that an error was occuring
trying to insert the images to OpenOffice.org. However the problem was
that the Insert Graphics dialog would not show the files. It turns out
that OpenOffice.org will not display images that have a .JPG (note the
uppercase) extension. I had to rename them to get OOo to show the file
names. I assume its a bug.
To try it your self run the following on a folder of .jpg files and try
to insert the graphic in OOo:
for i in nr*.jpg; do mv $i ${i%jpg}JPG; done
To return to lower case:
for i in nr*.JPG; do mv $i ${i%JPG}jpg; done
Obviously I can't guarantee the commands above but they worked for me.
