Abstract: Technology for generating thumbnail images is provided. In one example, a thumbnail image generation method may include receiving a request to generate a thumbnail image of an electronic page. The electronic page may be analyzed to identify content features of the electronic page. A determination of changes to make to a copy of the electronic page may be made based on the content features to form a modified electronic page. The thumbnail image for the electronic page may be generated using at least a portion of the modified electronic page.

Abstract: Techniques for scroll positioning of electronic documents, such as web pages, using element association are described. One or more first document elements associated with a first scroll position of a first document version may be determined. One or more first data representations of the one or more first document elements may then be generated. One or more second document elements may then be determined from within a second (i.e., reloaded) document version. One or more second data representations of the one or more second document elements may then be generated. At least one association between at least one of the one or more first data representations and at least one of the one or more of the second data representations may then be determined. A second scroll position for display of the second document version may then be determined based, at least in part, on the at least one association.
