Hi,
I'm working on a website writen in PHP (most of the files are PHP), including the index file.

there are a few buttons i would like to change in the index page (homepage), they seems to look like a rollover images,
but i can't find them as pictures in the website folders, so i went to the site and right clicked on the button i wanna change, then clicked on properties to check the name and the extention of the button
and the name i get is "info_pages.php?pages_id......" (seems like a php file)

I understand that some how those buttons i want to change or modify are planted in a PHP file
so HOW can i edit these buttons ( i am using Dreamweaver CS3)
i have an average knowledge in Dreamweaver and no knowledge in PHP or scripts (i just installed a Testing server once).

Please Help me as much as you can....Many thanks
