How can I see the dimensions of a photo in finder? I need cm or inches - not pixels!! "Get info" only shows pixel info e.g. "1200x 1400"...

An image doesn't have physical dimensions until you print it. It's physical size is dependent on the resolution which you use to print the image (i.e. the resolution of your printer).

A 1200 x 1400 pixel image is:

16.6 in. x 19.4 in. at 72 dots per inch (dpi)

12.5 in. x 14.5 in. at 96 dpi

6 in. x 7 in. at 200 dpi

you can use this script, save it as an application then just dro an image on it to see its size in CM @ 300dpi

on opentheFiles

-- start the Image Events application

tell application "Image Events" to launch

repeat with thisFile in theFiles

tell application "Image Events"

set this_image to openthisFile-- This 'open' has nothing to do with the handler name!

set the props_rec to the properties of this_image

set img_size to (dimensions of props_rec)

set {x, y} to the dimensions of this_image

-- purge the open image data

closethis_image

end tell

set img_width to round (item 1 of img_size) / 118

set img_height to round (item 2 of img_size) / 118

set img_printsize to "Image will print " & img_width & " cm X " & img_height & " cm" & " at 300 dpi" as text

set the image_info to (x * y)

display dialog img_printsize buttons {"Done"} with title "Your Image Info"

end repeat

-- Finished with Image Events.

tell application "Image Events" to quit

end open
