I want a box/frame/applet on my html webpage that will display an image and depending on where the user clicks i want text to popup/disappear somewhere else in the image. Does anyone know how to do this in javascript. Sorry Im new to web development and couldn't figure out how to do it in php. Thanks!

The above can be done through applet and no need for JavaScript. However if you insist on JavaScript solution of which I'm not sure can be done, then you are in wrong section (Java is not JavaScript) press Flag Bad Post option next to your original post and write "Please move to JavaScript section".

Kinger,
I'm away from home at the mo' and it's getting late. I'll post a DHTML solution a.s.a.p. It will employ HTML, CSS and JavaScript.

Kinger,
Here are three ways to do what you want using HTML and JavaScript, involving a mixture of mouseover and click events to cause text to be displayed.
Paste all the following code into a new text file - eg. test.html - then browse in your browser.
