Old links are no longer working

For a number of years I have used the following code to display a blank page containing a specified image when clicking on a thumbnail image:

It now calls up a totally blank page. Has something changed in php? html? When code has worked for a long time and suddenly breaks, I assume something in the system has changed that I'm unaware of.

Thanks for any information.

WELL! The pages that use this code have lots of other stuff going on too, so I made a new page that did nothing but show an image directly and call a blank page that displayed the same image when the thumbnail was clicked. Then decided I should look at the blank page code. It begins with checking for $_GET['img'] but also had a bunch of old and obviously outdated code which I stripped out before including here. Now the code works! What I stripped out was old code intended to protect against bad input (which I had gotten from somewhere when I first started web stuff & didn't understand).

I wouldn't have gotten here if I hadn't needed to show you folks my code. THANK YOU for being there!

Yes, exactly as I would have expected, mentioned and explained in my original reply to you but you went off on some other strange rant about much to do about nothing, before checking.
