*:I was just using the ''identify'' command from Imagemagick to get the pixel size of the images, subtracting 138 from the height, then scripting ''jpegtran'' to crop to that size. I agree that the metadata is important. ~~I'm going to look into the ''exiftran'' program. "It can do lossless rotations like jpegtran, but unlike jpegtran it cares about the EXIF data," says the man page.~~ I think the problem is that I didn't use the "copy all" option to jpegtran. --[[User:Rybec|Rybec]] ([[User talk:Rybec|talk]]) 04:39, 25 March 2013 (UTC)

*:I've manually uploaded to [[:File:1210_Turnhout_029.JPG]] one example of a file cropped with the "copy all" option. Its [http://regex.info/exif.cgi?imgurl=https%3A%2F%2Fupload.wikimedia.org%2Fwikipedia%2Fcommons%2F9%2F98%2F1210_Turnhout_029.JPG EXIF data] is preserved.
