Q&A

1. I'd like to know exactly which browsers support client-side imagemaps and which support server-side imagemaps.

   All browsers that display graphics support server-side imagemaps. All versions of Netscape Navigator and Microsoft Internet Explorer with version numbers 2 or higher also support client-side imagemaps. Any other Web browser produced after 1995 probably supports client-side imagemaps, too.

2. My imagemaps with polygonal and circular regions don't seem to work right in Netscape 2. Why?

   Netscape Navigator version 2 and Microsoft Internet Explorer version 2 only support rectangular regions in client-side imagemaps. Only people using version 3 or later of these browsers will be able to click non-rectangular regions.

3. I don't have Paint Shop Pro and my graphics software doesn't tell me x,y coordinates. How do I figure out the coordinates for my imagemaps?

   Here's a sneaky way to do it using Netscape Navigator. Put the image on a page with the ismap attribute and an <a> tag around it, like the following:

   <a href="nowhere"><img src="myimage.gif" ismap /></a>
   

   When you view that page with Navigator, move the mouse over the image. You will see the coordinates in the message box at the bottom of the window.
