 <p>Gibberish,</p> <p>Try the <strong><a href="http://www.outsharked.com/imagemapster/" rel="nofollow">ImageMapster</a></strong> jQuery plugin, which acts on image maps to offer (at v1.2.6) the following features :</p> <ul> <li>Highlight and select areas</li> <li>Cool effects by using an alternate image</li> <li>Bind the image map to an external list</li> <li>Show floating tooltips for areas or area groups</li> <li>Grouping and exclusion masks to create complex functionality</li> <li>Automatic scaling of imagemaps to any display size, even while active</li> </ul> <p>The feature you need is the last one listed.</p> <p>I've not used ImageMapster myself, but the <strong><a href="http://www.outsharked.com/imagemapster/default.aspx?demos.html" rel="nofollow">demos</a></strong> are very impressive and indicative of a well written plugin.</p>
