On the File search results page put your mouse cursor over an image you will see a button in the bottom right corner for 'More'.
Clicking this will reveal a larger view of the image and some of the 'File info'.
There are also another 2 tabs: 'Sizes' and 'Similar'
The Sizes tab lets you see the alternative sizes for that file. From here you can download the file or copy a link to the File if your user permissions allow.
The similar tab will show a number of images that are similar to the one you are looking at. The similarity of these images is calculated via AI-driven image recognition. You are able to add these images to your Selection by clicking the blue check buttons if you wish.
