Samsung S7 Edge - Arrow ccon on top corner in photo gallery

[MoonJ90]

Hi all!

I've noticed that when I take a photo there is a white arrow icon on top of my photos. Just wondering if anyone knows what it is and how to disable it?

Below is a link of a screenshot I took:

Thanks!

Any way you can post a screenshot to this forum? Whatever third party link you had in your post redirects to something shady. I have block pop-ups on as well.
