The Emacs mail client VM (http://www.wonderworks.com/vm/) divides images into strips to allow scrolling. From the documentation of vm-mime-use-image-strips: *Non-nil means chop an image into horizontal strip for display. Emacs treats a displayed image as a single large character and cannot scroll vertically within an image. To work around this limitation VM can display an image as a series of contiguous horizontal strips that Emacs' scrolling routines can better handle. To do this VM needs to have the ImageMagick programs 'convert' and 'identify' installed; `vm-imagemagick-convert-program' and `vm-imagemagick-identify-program must point to them. A nil value means VM should display images without cutting them into strips. Does that sound like it would be of use?
