It doesn't :(
Chrome 11.0.696.71 and FF 4.0.1
The popup seems to be working but the image is 100% size and not scaled at all.
I'll see if I can get you any more details.
Yes, showing as gigantic popup covering entire window, and yes it's inside <script> tags. I should've added the tags on here.
The content was being pulled from an MySQL db by PHP but I've just tried it with one of the same image files in a plain HTML file and it still happens.
Found a problem. I have a long page with 3 images/thumbs on it at different points down the page. First image/thumb is near the top, have to scroll to get to the other 2.
When I click the top one the popup appears half way down the page and I need to scroll down to see it.
Are you having the popup appear at the middle of the page height/vertical wise, rather than at the middle of the window?
body { overflow-y: scroll; }
Nope :(
I've updated the test and you'll see if you click the bottom one it extends the page below the normal length of the page.
