If an image has been cropped horizontally, writeImageBlock detects that its width and Stride differ and acts accordingly. However, if an image has been cropped vertically, trimming from the bottom, the whole original image will be written in place. This results in more data in the LZW stream than necessary, and many decoders including image/gif's itself will fail to load.
