Yes, you were right, this works just the way you wrote.
And yes, there is a JavaScript way to do it, but I guess PHP is better for
this kind of jobs. JavaScript is using your browser as it's 'server' while
PHP uses your remote server. Therefore, all PHP will do is generate HTML
code to send to client. Make a way it dynamically assigns you the right
image and, vuala! Just if you would have coded that HTML page yourself. No
JavaScript.

Subject: 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?
Thanks
Kynan
