How to open image in full screen mode vs. split screen on side

When I searched images I on my old iPad I was able to click on the image to view it in full screen mode without having to open the website and I could swipe to move to the next image, again without having to open the website. My new iPad opens images on the side as a split screen so the image is still small. If I want to view it larger I have to open the website, which I do not want to do. How do I get images to open in full screen mode vs. opening on the side? Turning off Allow Multiple Apps does not fix this issue.
