I'm trying to write a folder action and I need a little help...

I have a directory for my web site called "originals" which contains PNG graphics, and I'd like to have a folder action that automagically compresses the files with the built-in Finder "Create Archive" command, and deletes the original PNG image.

Can anyone help? I'm clueless.

What event would trigger the compression? When new .png files are added? Is this a one time occurence? A bit more info will help.

Start here:

Your folder action script will most likely use the "do shell" command to archive items with the "compress" command or something similar.

BTW, the new Script Editor in Panther supports contextual menu scripts that can insert code snippets into a script for you automatically.

Click in a new script window with the control key down and select "Folder Actions Handlers > Adding to Folder" to insert the Folder Actions handler for the added items event.

Something like this. Note that you must move the added items to another folder to keep the folder action from being triggered again when the item is compressed.

Code:
on adding folder items to this_folder after receiving these_items
	tell application "Finder"
		if not (exists folder "Done" of this_folder) then
			make new folder at this_folder with properties {name:"Done"}
		end if
		repeat with i from 1 to number of items in these_items
			set this_item to item i of these_items
			set this_item to (move this_item to folder "Done" of this_folder with replacing) as alias
			set the POSIX_path to the quoted form of the POSIX path of this_item
			do shell script ("compress " & POSIX_path)
			delete this_item
		end repeat
	end tell
end adding folder items to
