Funding opportunities and digitisation initiatives offer libraries, galleries and museums the potential to exploit their image collections – photographs, slides, drawings, pictures and works of art – in new and exciting ways. Many different organisations are involved in developing standards for the formal description of images (e.g. artist, title, photographer) and some effort is being made to develop compatible standards for the digital environment. Indexing of images can be a difficult task because images are rich in information and may be used by widely different groups of users, who may not always express their information needs adequately. Content-Based Image Retrieval (CBIR) technology, which allows the retrieval of images based on similarity to a query image, has enormous potential, particularly if it can be combined with text-based indexing.
