Hey Jeroen,

Thanks for the code pointer, I'm going to nick that because it's
handy to have around. Less handy are the two memory leaks though. :)
scriptError and appleScript both leak - they're sent allocs but have
no matching release or autorelease. Also, even when you add a release
for the scriptError it'll leak anyway. :) executeAndReturnError: will
overwrite the pointer to the dictionary with the dictionary it creates
internally. It's not a very common idiom in Cocoa ( although there are
a few places that do use it ) but it's something to watch out for.

Here's the adjusted code below. Thanks for putting it up - the
image color automater thing is a very cool idea by the way. Try adding
face recognition and it'd be super-duper cool. :)

Take care,

Guy
