How to display information on rollover image like facebook people taging

I wonder if anyone can post a code example on how I can display some information when I hover a certain pixel cordinate on an image (just like when I hover a picture on a facebook image and it displays a text of who that person is that I currently have my mouse pointer over).

The diffrence between fa开发者_高级运维cebook and my solution is that my picture is not a picture which contains people, but multiple graphs on same picture, so alot of image pixelcordinates is going to display some data when I hover over them.

I also want my sollution to be webbased, and if possible only contain javascript, jquery css html.

Thanks so much in advance =)

But to answer your question "...wonder if anyone can post a code example..." i've done this:

HTML

<img name="n00000001" src="http://ajthomas.co.uk/shapes.png" width="300" height="300" border="0" id="n00000001" usemap="#m_00000001" alt="" /><map name="m_00000001" id="m_00000001">

<area shape="rect" coords="28,179,116,256" href="#" title="square" alt="square" />

<area shape="circle" coords="228,66, 45" href="#" title="round" alt="round" />

<area shape="poly" coords="60,32,22,72,51,120,104,109,111,54,60,32" href="#" title="Poly" alt="Poly" />

I've put it on jsfiddle for you too - http://jsfiddle.net/ajthomascouk/xsrzz/

I used fireworks, but i'm sure there is free tools out there too.

Hope this helps.

Update

i'm sure there is free tools out there too.

Yup, Gimp can do it using this plugin

Good luck...
