Just checked it on an iphone, ipad, mac laptop, firefox on a windows desktop and IE and everything looks good. Can you email me a larger photo of that so I can see it better. jeff@jungletraining.com
I get those usually on multiple picture posts Using iPhone I only see them I have not attached anything.
I've never seen that overlay icon that is repeating itself in your screenshot. Looks like a plane with paratroopers. I will look to make sure there is no image overlay showing up in the dark themes for the forum background.
I just checked all the icons in the style sheet and that particular one does not show up anywhere. Cool icon though. Looks all military and stuff.
No one else is reporting it so I'm wondering if it's somehow migrating from your local device. I will do some more checking in the styles later tonight but not being able to reproduce it with more than one member makes it difficult. Have you ever seen that icon before elsewhere?
