I embedded HTML page/view to website with photo and text input. It's working fine and exit the ZC app and the website.

When I open the website again the next day, the photo column is blank. So I click the edit and changed photo, it was reported, "data added successfully" but the photo column still blank. But when I opened the ZC app, the photo was there. Without doing any changes, I returned to the website, and the photo appeared.

Is the source app of embedded HTML page to website should be set share to public? 

or

Is the photo in embedded page to website is visible only when the source app is also open?

Thanks,
