This version fixes a big memory leak in the file access code.
See the Version History for a more complete list of changes.
The only major new features in version 1.6 from 1.5 is the ability to place the object information that normally goes in a .map file within the HTML of the page housing the graphic, thus allowing for many many pages to use the same graphic, but have its buttons link to different files in each place.
A very good example of this (and in fact, the reason I added it) is the story pages of the Electronic Collegian (http://www.spub.ksu.edu/). Beginning with the Summer '95 issues, each story has an imagemap bar at the top and bottom where the "Previous aritcle" and "Next article" buttons are different on every page, which would require a separate .map file for each story. By placing the info in a form element on the page with the imagemap graphic acting as the Submit button, no .map files are needed.
Most graphical browsers that I've tested work with this method, although there are probably a few older ones that don't.
