Open an image in fullscreen

[joomlabc]

I'm developing an Iphone application displaying webpages from several tabs. In some HTML pages I have images. I would like to allow users to click on the image to be display it in full screen mode with the Close button on top left. User should also be able to see other images from the page with the slide functionnality of the iphone.

How can I do this? What kind of code do I have to put into HTML file ? Do I have to use Javascript ?

Thanks for all your advices.

You will probably need javascript.. You will have much better luck asking this in a javascript forum, when you ask there you probably willn't need to mention this is for an iPhone but then again, it can't hurt.
good luck!
