Nubie scripting question

I would like to set up a situation where I have one main page with a bunch of thumbnail pictures on it. Each will have a link to a larger photo. However, rather than just simply loading a raw JPEG to a blank page, I would like to use PHP, so that each link will point to 1 main php display page - that I can program to look nice and display all the images from this one page - one at a time - of course. So - the thumbnail links would look something like this: <a href="http://www.mydomain.com/display.php?pic=pic1.gif" ><img src="pic1thumb.gif" alt="deals"></a> This URL addition: ?pic=pic1.gif (will carry the name of the picture to be loaded) Q: here is what I am unclear of: since I do not know PhP - how do I get the main display page to read this part of the URL? <img src="??? Url.pic ???" alt="deals"> - how do I write this? thanks in advance for your help -- Thanks - RevDave Lists@domains4days.com [db-lists] Check out some great Domain Names at: http://www.domains4days.com
