Techniques involve visually summarizing documents (e.g., search results, a collection of documents, etc.) using images which are visually representative of the documents for which the images represent. The images representing the documents may be external images obtained from sources other than the documents. The external images may be obtained from the sources other than the documents by performing a separate image based search using key phrases from the documents rather than extracting the images directly from within the documents themselves. Alternatively, an algorithm may be used to determine an image type, which may be chosen from a selection of external images, thumbnail images, or internal imaged taken directly from the collection of documents, that is suited to represent each document in the collection of documents. A snippet of the documents may be displayed along with the images which visually represent each of the documents.
