Two ways.
First. Use a <u>java applet</u> that does it all for you. You just have to read the notes and configure it. You can get loads of free applets at places like these:
http://www.javagoodies.com/ http://www.cdsony.com/java.shtml http://javaboutique.internet.com/ http://www.javapowered.com/ A word of caution: not all applets are equal and some are prone to generate errors.
Second. You can use a bit of <u>javascript</u> to automatically swap alternate graphic images that you create. For a big site, this is a lot of work but the effect can be very nice. To see an example of this at work, take a look
here where I helped a few friends put this together. It's all done graphically with extensive use of the mouseover, mouseout, mousedown, mouseup commands. I created this, for the most part, using
macromedia's dreamweaver program. But it needed tweaking too. To learn a bit about what's behind this, take a look
here . Browse the site, there's a lot of good info.
Lastly, something you didn't ask was image maps. That's where there's one graphic, but different parts of it link to different pages. Can be nice.
