resize all images in folder and create new images (w/o overwriting)

for file in *; do convert $file -resize 800x600 resized-$file; done

To ignore aspect ratio, run: for file in *; do convert $file -resize 800x600! resized-$file; done and all images will be exactly 800x600. Use your shell of choice.. This was done in BASH.
