RE: [PHP] newbie question about variables

Hi, I have not coded script in html before, so I was wondering if someone could look this over briefly: I'm a bit confused as to how variables are passed/stored. Do the variables get saved on the client machine? Do they have to be specifically passed from page to page and back? Are they automatically returned to the calling page? If I have a page with thumbnail, and I'd like to call a page that dynamically places the original photo into it (based on the thumbnail clicked) does it go a little something like this? in index.html: <a href="picture.html?var=pictureone.jpg"><img src="thumbnail.gif"></a> in picture.html <a href="index.html"><img src="<?php print $var ?>"</a> Is there a similar javascript method?
