I have a page that contains a map image.

On top of this map image I wish to float another graphicor multiple graphics to show the position of an event. I can happily place one image on top of the other but I cannot gurantee the position of the map on the page so I need to position the floating graphic relative to the position of the map.

So..
How do I find the current position of the map?
How can I then use this to position the image(s) relative to the map?

Andrew,

You need to put all the images inside a container, and make the positions relative to that container.
The container should be the same size (in pixels) as the map.

<html>
 <body>
 blah BEFORE blah
 <div id="container" style="position:relative; height:400; width:200;">
  <div id="map" style="position:absolute; left:0; top:0;"><img src="map.gif" height="400" width="200"></div>
  <div id="img1" style="position:absolute; left:15; top:15;"><img src="beacon.gif" width="10" height="10"></div>
  <div id="img2" style="position:absolute; left:55; top:55;"><img src="beacon.gif" width="10" height="10"></div>
  <div id="img3" style="position:absolute; left:55; top:15;"><img src="beacon.gif" width="10" height="10"></div>
  <div id="img4" style="position:absolute; left:15; top:55;"><img src="beacon.gif" width="10" height="10"></div>
 </div>
 blah AFTER blah
 </body>
</html>

You can also specify the z-index, but this is unnecessary in this case, as the browser will put elements defined earlier behind the elements defined later.

Good Luck,

Brian

Thanks Brian

It works a treat. In fact I found that I didn't have to put the images into their own divs merely have them in the container div.

Keep in touch
