Hi!

I did it but … maybe to late for you.

Script code:

global theImage


-- Prompt the user to select a file

set theImage to choose file with prompt "Please select an image file:" without invisibles

-- Prompt the user to enter the width of the picture

set theResult to display dialog "Saisissez la largeur de l'image." default answer "640"

set theAnswer to text returned of theResult
-- Retrieve the resize percentage amount

set theNewWidth to theAnswer as integer
-- Determine a path in which to save the resized image

tell application "Finder"

	set theImageName to name of theImage

	set theImageFolder to (folder of theImage) as string

end tell

set theResizedImagePath to theImageFolder & "Resized-" & theImageName as string
-- Open the image, resize it, and save it as a new file

tell application "Image Events"

	launch

	set theImage to open theImage
	-- This is the tricky part: you need to keep the ratio of the original picture

	copy dimensions of theImage to {currentWidth, currentHeight}

	set ratio to theNewWidth / currentWidth

tell theImage scale by factor ratio to size theNewWidth save in theResizedImagePath close end tell end tell

You could use an external program to shrink them. I don’t use the system outlined above, as I don’t post that many images.

What I do use is something called PNG Compress (or similar) to shrink PNG images. JPGs I generally will process with Photoshop/ImageReady.

It would be good to see how small a file Lightroom makes. You can, after all, generate a whole Web Gallery from that, and can export just one image if you prefer.

The downside is the resultant resized images are not compressed enough and are still way too large (in file size) than they would be had I resized them with an external application.

I use Resize! to batch resize AND compress images. Apple seems to have forgotten the compression side of things.

Still, I use Automator regularly for other stuff and it really is a cool way to get dross things done.
