Lightbox on index page show

[ptlycldy]

I'd like to have a image on top of the index page every time the index page is shown. I tried using an event in the index page properties, selecting event->onload, action->link, and inside the edit screen chose link to->page in this project. However, I don't see a way to select a lightbox to display the "page in this project". I'd like to use the lightbox because of its ability to be closed: the X in the upper right corner. Clicking that X would bring me back to the index page.

Obviously, a lightbox is not the way to go. Can someone point me to a way to put a "popup" containing a image that would overlay the index page that can be dismissed, but would popup again when the index page (home) was called up again?

Thanks for your help.

Have you tried using a modal layer?

Thanks, Crispy.
Hadn't used a modal layer before. Looked it up and it looks like it will do the job from the YouTube video I saw.

Thanks, again.
