Quark image resolution

I need to get the resolution of linked images in Quark6.5, but the code below returns nulls. If, in a Quark doc, you check the Usage box and click on “More information”, it shows the image resolution and its width, heigth and DPI in the last line called “Dimension:”. Anyone know how to get the info so I can divide it by the scale factor to get final resolution of the images?


tell application "QuarkXPress"
	tell document 1
		repeat with thePic from 1 to (count of picture boxes)
			tell picture box thePic
				get name of image 1 -- returns null, see result below
				get file path of image 1
				get scale of image 1
				--get dimensions of image 1 -- does not work even though Quark usage box in the "More information" area labels the Height, Width and resolution as "Dimension"
				get actual bounds of image 1
				get bounds of image 1
				try
					get color TIFF resolution of image 1-- returns null, see result below
					get gray TIFF resolution of image 1-- returns null, see result below
					get resolution of image 1 -- does not work
				end try
								
				

			end tell
		end repeat
	end tell
end tell

RESULT:

tell application “QuarkXPress”
count every picture box of document 1
