I found an issue with sharing galleries. My original thread was here where you helped me share galleries between sites.
Using the URL as suggested in the original post works except for the following:
The Gallery screen adds a Back button at the bottom - see this image.
When you click the Back button, the gallery displays the entire current screen inside the gallery window.
You can see the issue on this page. Scroll down a bit to see the gallery.
Can you please help?
