convert or mogrify is probably the easiest.

It complains for two reasons:
1) The options are supposed to come before the input file (though it
might be smart enough to figure this out; and
2) Your -resize option is under-specified.
Try
convert -resize 10x10% image.JPG images.jpg
or
cp image.JPG images.jpg
mogrify -scale 10x10% images.jpg
I have a perl script that generates web pages for digital photos that
includes the snippet:
foreach $a (@files)
{
`cp $a small/`;
`mogrify -scale 30x30% small/$a`;
`cp $a thumbnail/`;
`mogrify -scale 4x4% thumbnail/$a`;
...
}
That's for 5Mpx images, which is why the thumbnail size is only 4%.
