Google Photos for web now shows if your images are taking up space
 

Google has introduced a small but very useful change to Photos on the web, spotted by 9to5Google. In the info section for each photo, there's a new category called "Backed up" after the current day/date, location, device, EXIF and image size. It shows whether the file has been saved in "Original quality" or "Storage saver," and how much space it's taking up, if any.
