iPhone 6 won't allow me to paste images into img tab.

There were a few threads on the tech board about this. I think it's the latest iOS update.

There's a way to get around it on google images, but I don't know about images from other sites.

On the Google image search, hit the three white dots located near the lower right, then view image. Copy url and paste.

Disclaimer: I think that's the way to do it.
