from the below If I load 1 image _id shows the number 1, then I delete image from viewer and load
another image _id shows 2, and so on so I am guessing that it will just keep counting the amount of
images that I have loaded etc, cant seem to get much more than that at the moment.
set _id to id of image of image view “bigimg1” of window “mainWin”
delay 1
tell application “Finder”
display dialog _id
end tell
