Here is how I do it, using ImageMagick:

-- Rev function that uses ImageMagick to get the dimensions of an image
-- returns width,height
--
function picSize pPicPath
	-- ImageMagick command: identify pic.jpg
	-- returns: pic.jpg JPEG 640x480 DirectClass 87kb 0.050u 0:01

	put "identify " & pPicPath into tCmd
	put shell(tCmd) into tSize
	put word 3 of tSize into tSize
	replace "x" with comma in tSize

	return tSize
end picSize

Cheers,
