1. A method to mark traversed hypertext clickable image links on an image map, comprising the steps of:
- (a) retrieving a history of the coordinates of at least one hypertext clickable image link on a hypertext image map having a plurality of the hypertext clickable image links, of which at least one of said image links has been traversed;
(b) determining if the image map has been modified since last viewed;
(c) if not, modifying the image map at or substantially near the coordinates of the at least one traversed image link with at least one marker;
(d) displaying the image map with the at least one marker.

Abstract
The invention is a method to mark hypertext links in an image map that have been traversed. The invention actually modifies the image map of the links by inserting a marker or changing the color associated with the coordinates of a particular image link on the image map. The history files of links that have been traversed are first checked to determine if the image has changed or is otherwise out of date. The image map or a copy of the image map is then modified and displayed.

8. A method to mark traversed hypertext clickable image links on an image map, comprising the steps of:
-
(a) retrieving a history of the coordinates on an image map indicating the position of at least one of said hypertext clickable image links that has been traversed, said image map having more than one hypertext clickable image links; (b) determining if the image map has been modified since last viewed; (c) determining if the last time the image map was viewed precedes a preset user timestamp; (d) if neither (b) nor (c), then modifying the image map with a marker by modifying the pixels at or substantially near the coordinates of the at least one traversed image link to create a bit map image of the marker; (e) displaying the image map with the marker.

9. A method of marking traversed image links identified by coordinates on an image map, comprising:
-
(a) retrieving a history of the coordinates identifying at least one image link that has been traversed on an image map having a plurality of said image links; (b) determining if the image map has been modified since last viewed; (c) if not, copying the image map; (d) modifying the copied image map at or substantially near the coordinates of the at least one traversed image link with a marker; (e) overlaying the modified image map onto the original image map. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method to mark traversed hypertext clickable image links each having respective coordinate on an image map having a plurality of said hypertext clickable image links, said method comprising retrieving a history of the respective coordinates and modifying the image map at or substantially near the respective coordinates that have not changed of each traversed image link on the image map.

17. A computer browser to traverse hypertext links, said browser comprising:
-
(a) means to generate an image map having a plurality of clickable hypertext image links; (b) means to retrieve a history of the coordinates Of the clickable hypertext image links on the image map; (c) means to place a marker on the image map at or near the coordinates of at least one of the clickable hypertext image links that has been traversed and whose coordinates have not chained; and (d) means to display the image map having the marker.

18. An article of manufacture, comprising a data storage medium tangibly embodying a program of making readable instructions executable by a digital processing apparatus to perform method steps for operating a digital computer system to mark traversed image links identified by coordinates on an image map, said method steps comprising the steps of:
-
(a) retrieving a history of the coordinates on the traversed image links on the image map, the image having a plurality of image links; (b) determining if the image map has been modified since last viewed; (c) if not, copying the image map; (d) modifying the copied image map at or substantially near the coordinates of the traversed image links with a marker; (e) overlaying the modified image map onto the original image map.
