How do i upgrade Applescript from 1.9.3 to 1.10.7?

Basically, thats the thing. Let me explain…
We have several Macs in the office, and the server is running on Panther and has the Applescript 1.9.3. Recently i’ve made a script for that server, to classify images on our image bank, and to rename them and that sort of things (thousands and thousands of images), but i never realized that my Applescript ( 1.10.7 ) was a different version of the one on the server.
So, the thing is I need to upgrade Applescript, but without upgrading the OS.
Any ideas?

Side question: Would the Image Events also upgrade? if not, how do i get its version, and, if needed, how do i upgrade it?

thnaks guys.

I don’t think you can do that.

That would probably be included in a system update if it was needed.

Also, I believe most, if not all, applications have a version property:

tell application "Image Events"
	return version
end tell

If it matters, I’m on OS X 10.4.7, and have Image Events 1.1.
