Soory posted without tags…

I’ve notice this bug also. If somebody want to workaround it just use SPAN tag with IMG tag inside and in change map function assign innerHTML attribute with String

I’ve actually stopped using img maps altogether. There are still certain cases where they can be useful but you can also just place normal links over them by using absolute positioning.

Just some clarification re. my understanding of this issue:

The problem occurs when you try to dynamically create poly areas which have different numbers of co-ordinates. Basically, if you have 2 poly areas, and the second one has fewer co-ordinates than the first, the 2nd area will crash IE6/7.

The fix is to create your IMG tag using innerHTML rather than DOM element properties.

ie this *won’t* work

var map_image = document.getElementById(’map’);
map_image.src = ‘images/maps/’ + map_file;
map_image.isMap = ‘ismap’;
map_image.useMap = ‘#layer’ + parent_level_id + ‘_map’;

Whereas if you put your IMG tag inside a SPAN, like so:

and update it like this:

var map_image_span = document.getElementById(’map_image_span’);
map_image_span.innerHTML = “”;

You should be fine.

Thank you!
I had traced the crash to be related to the image, but would have used a lot more time to find out it was the image map.

You saved my day :D
