I have a PHP page with a Javascript image popup function in the <head>
area. Page layout is by CSS. You can see it here:
        http://www.allnovascotia.com/test/sandwichchef/index.php
Menu buttons on the side reload the page, and a value passed in the URL
controls what is loaded and displayed in the centre column.
If the page is loaded with NO query string, just
.../sandwichchef/index.php the popup works fine. If Ctrl+R is pressed to
reload the page, no problem.
If the page is loaded WITH a query string (or one of the buttons is
clicked), such as ../sandwichchef/index.php?pgget=1, the popup script
executes, but no picture is loaded , just a black box with a missing
image symbol.
Nothing shows up in the Javascript console.
Is the problem the reliance of the popup code on passing an URL, but the
browser already has a different query string stored?
Here's a link to the main page:
        http://www.allnovascotia.com/test/sandwichchef/index.phps
The included files contain nothing but text.
The popup page (popPic.htm) is v. short and is presented below my
signature.
I'm really puzzled and suggestions / guidance will be most welcome.
