    Default Thumbnail viewer in iframe - images wont appear on top

    Hey all, I'm not all that good with this css stuff and what not. I've got a gallery page on my website which uses the thumbnail viewer. However I just redid the site and now that page is in an iframe. I'd like the images to appear over everything. How can I achieve this?

    You can see it at www.offtrailphoto.com

    Heres the js? I don't even know what that means.

    The images are in the iframe, so I'm not exactly sure how you'd achieve this, you would need to attach the images to the page you're actually on instead of the iframe.

    And for next time, make sure you put the code you've submitted between the [CODE] tags, to make it easier to read and also so you don't end up with "" in the code lol.

    The images are in the iframe, when you click them, thumbnail viewer makes them bigger, but, i dont want the in the iframe because then you have to scroll the frame all around to see the whole image, i want them to open large infront of everything... that didn't work.

    Yes, I know, I've since edited the post, as I realised what you meant, I'm looking into how to solve it.
