Safari won't let me save pictures when I press and hold the picture

I Want to save a picture from safari, by pressing g and holding down, it always worked for me but now all of a sudden when I press and hold down the picture planning on saving it, instead it comes up with the zoom to magnify words. (the small little box). I've looked everywhere in my settings to turn something off but nothing works. Please help... I can't save pictures from safari. I have an iPhone 6 iOS 9.0.2. As you can see on the picture below it shows what it does to be.
