Imgur?

[A.L.]

When you get to the post you want and see the picture you want just click on the picture again 1 more time and the full screen pic goes partial size and has a black border and an X in the upper left

Then you can click on the little share arrow there to get the URL with the .jpg extension

When using the image symbol on BF, be sure you are pasting into the second tab with the chain link/infinity symbol

That worked, thanks a lot!
