I tried opening that same URL in firefox, chrome, safari, Ur (that's a browser!), and torbrowser (via sweden) on my iMac, logged in to billiongraves as me, having uploaded the photo from the billiongraves app on my phone, using the same login. In none of those browsers can I see a pencil icon in the grave site section.
"Big Photo" problem? Sorry, I don't understand. I don't see any message about a big photo. What should I see? Can you post a screenshot??
