Expanding thumbnail with metadata overlay

A computer program product, encoded on a tangible program carrier, operable to cause data processing apparatus to perform operations comprising:

• displaying on a display device a collection of thumbnail images in a graphical user interface, each thumbnail image representing a distinct selectable product or service;
• receiving user input moving a cursor displayed on the display device;
• determining whether the cursor is positioned within a region associated with a first one of the thumbnail images, and while the cursor is positioned within the region, displaying an enlarged version of the first thumbnail image, the enlarged version having a boundary and including an overlay confined within the boundary of the enlarged version, the overlay at least partially covering the enlarged version and displaying (i) data associated with the product or service represented by the first thumbnail image and (ii) a pull-down menu for performing at least one action on the product or service represented by the first thumbnail image;
• and
• removing the enlarged version responsive to when the cursor is no longer positioned in the region.

• display on a display device a collection of thumbnail images in a graphical user interface, each thumbnail image representing a distinct selectable product or service;
• receive user input moving a cursor displayed on the display device;
• determine whether the cursor is positioned within a region associated with a first one of the thumbnail images, and while the cursor is positioned within the region, display an enlarged version of the first thumbnail image, the enlarged version having a boundary and including an overlay confined within the boundary of the enlarged version, the overlay at least partially covering the enlarged version and displaying data associated with the product or service represented by the first thumbnail image and (ii) a pull-down menu for performing at least one action on the product or service represented by the first thumbnail image;
