convert all *.ps to PNG format by a script

1. ONLY convert the files in the directory where this script is.
2. “-density 150″ is the resolution, in this case 150 dpi
3. -geometry 100% is the scale you want to resize by %
4. also, you can convert lots of JPEG to smaller resolution, just change .ps to .jpg, and change the output to another directory, either using .jpg or .png

———— following lines are the content of the script ———

#!/bin/sh
