Help! Resize & Upload images script fails only about 50% of the time!

Hello to all,

I am a scripting newbie, and I am in need of some help. I wrote a script (droplet) to take any number of images that are dropped onto the icon, duplicate them into a new folder (so there are originals that are untouched), scale the images using ImageEvents, then upload the web-friendly sized pics to an afp mounted share point.

The script works many times, but often it fails! I cannot figure out a rhyme or reason to why it fails. I used a bunch of on error commands to help me determine WHERE the script breaks down (it is notated in the script), but I cannot figure out WHY it fails sometimes and other times it works like a charm.

Any help would be appreciated.

Thank you,

Dave Huber

Not that this is any help to your direct request, but I have never had any consistent luck with Image Events.

No rhyme or reason, but sometimes it just doesn’t work for me. I always thought it had something to do with the images I was using, but sometimes a particular image will process, other times it won’t.

Image Events certainly some quirkiness associated with it. Nigel Garvey posted this script in another thread that has worked well for me to overcome some of the erratic behavior.

set main_path to (path to desktop as Unicode text)
set a to (choose file)
tell application "Image Events"
	close images
	set b to (open a)
	set {{c, d}, e} to {dimensions, resolution} of b
	scale b by factor 0.2
	set p to main_path & name of b
	save b in file p
	close b
	
	set b to (open file p)
	set {f, g} to dimensions of b
	close b
end tell

get {c, d, e, f, g}

The two main differences are the close images and save b in file p commands. Try those out in your script and see if that improves reliability.

Some snippets of the script aboved worked like a charm, and it also allowed me to get rid of some bloat in my own script. THANKS SO MUCH FOR THE HELP!!!
