When I long press on an image I get two options: Save Image or Copy. Pre iOS 8 if you tapped on copy it would copy the image url. It no longer does that in iOS 8, except for a select few websites (like Twitter). Most times if you select copy it does absolutely nothing. Very annoying. And I also noticed that the text selection is the same as it was before this latest update so that was not fixed (at least for me).
