You can use a nifty program called Mapedit.
It looks like a commercial website and it IS. You have 100 savings of your work when you install a free version and you have 30 days. If you are doing it at school or at work, just ask an image or go install it on a different pc when the 30 days or 100 saves are finished.
The problems with imagemapping is that you must create a per-poly line that creates a line between the pixel-points you insert. Without mapedit you will have to go with Photoshop or paint and search for the coords where you want the links to be inserted. The one and only reason to use imagemapping is because it looks nifty, look at my website:
http://www.freewebs....esper_portfolio and look at the menu, it were rectangles first that were cut off on the middle and placed ontop of eachother (with the bare eyes, it is hard to tell were the middle is when you don't know the original, that is why I created a "how-it-was-before" copy of it on a different URL: http://www.freewebs....sper_portfolio2 )
The difference this site with the other site is that when you keep your cursor on the left and right side of one of the images in the menu, you will be on the brown part and still select HOME, while the brown part should direct to HARDWARE.
Only THIS page is with the old menu, all others have been replaced, due to webspace. The links are working and will take you to my new one.
I hope I have made some things clear for web developers. I will check this topic for updates every day, to see how I can help more with this special feature of HTML.
