So someone suggested a image map for me to use.
I just can't figure out my co ordinates for this.

I'm using this basic code: Click.

So how do I figure out my co ordinates for my link areas?

Any help would be great. Thanks.

Ok, I did the firefox measrueing, and I still don't think I have it right.

Here's my final code:

CODE

<DIV ALIGN=CENTER>

<MAP NAME="map1">
<AREA
   HREF="http://tammys-tackshop.webs.com/index.htm" ALT="home" TITLE="home"
   SHAPE=RECT COORDS="87,23,82,22">
<AREA
   HREF="http://tammys-tackshop.webs.com/bio.htm" ALT="bio" TITLE="bio"
   SHAPE=RECT COORDS="53,26,48,24">
<AREA
   HREF="http://tammys-tackshop.webs.com/gallery.htm" ALT="gallery" TITLE="gallery"
   SHAPE=RECT COORDS="106,23,100,20">

</MAP>

   ALT="map of GH site" BORDER=0 WIDTH=300 HEIGHT=300
   USEMAP="#map1"><BR>

</DIV>

When I put it on my site, I have nothing there.
