No - not quite the same! In the 'Popup-Iframe.web' example the text panel is on the base page and the pop-up pages are loaded into it - the text panel stays the same. My page/s however has/have no text panel visible to start with - only as Pop-ups. And there is the ability to have visual variety of position on the page for each pop-up.

The advantage with the gallery text panels is that they are auto-stretch to fit whatever length text. But in the iframe method this might result in having to scroll which looks a bit odd on certain types of panel.

But I'm not knocking it yet - I haven't yet had a go to see if I can adapt it to achieve the result I have with converting the text panel to a graphic image. So far I have my reservations but it is a very good work-around anyway for certain situations.
