Need help with Folder Actions

:smiley:
Hi to everybody,
I’ve posted this request also in Mac OSX section of this BBS.
As I wrote there I’M A NOVICE in scripting, but I found very useful using FOLDER ACTIONS SCRIPTS for my job.
I need to wrote a script which resize images resolution i.e. from 300 dpi to 150 dpi as I move or copy them into my destination folder.

-Do I have to involve applications like Photoshop or similars?
-Can you suggest me any other way to do this kind of operations using other scripting features? :rolleyes:
-What is the best manual today in commerce?

THANKS A LOT TO EVERYBODY WHO CAN HELP ME.
