Digilib is a web based client/server technology for images. The image content is processed on-the-fly by a Java Servlet on the server side so that only the visible portion of the image is sent to the web browser on the client side. It supports a wide range of image formats and viewing options on the server side while only requiring an internet browser with javascript and a low bandwidth internet connection on the client side. digilib enables very detailed work on an image as required by scientists with elaborate zoom features like an option to show images on the screen in their original size. digilib facilitates cooperation of scientists over the internet and novel uses of source material by image annotations and stable references that can be embedded in URLs. digilib is used in the ALCATRAZ framework of image, text and annotation tools and many other projects.

GIMP is image editing software, much like Photoshop. It is a multi-platform software application primarily used for image composition and editing. The basic tool may be augmented by plug-ins and extensions that allow the use of new file formats, effects filters and batch processing capabilities. GIMP was initially created to manipulate raster images, but has been extended to provide limited vector image and moving image support. A number of free extensions are available in the plugin registry.
