This shows that the image in question has been selected.

The thumbnail will be indented with a blue-grey border and a blue checkmark will appear in its top-left corner. When looking at the grid of thumbnails in the Google Photos app, press and hold on the first image you’d like to save. Saving several snaps from Google Photos to your iPhone at the same time is a slightly different process – but just as simple. How to save multiple photos to your iPhone If you don’t see a ‘download’ option in the toolbar, it’s almost certainly because the image is already saved to your iPhone’s camera roll. To help save data and prevent duplicates, the download option won’t appear for shots that you’ve already got. With the option turned on, Google will check your iPhone’s camera roll to see which snaps are already saved to your device.

You don’t need to enable the backup and sync setting to save single shots from Google Photos to your iPhone, but it can be helpful. Head to your iPhone’s default Photos app and you should see the photo you just downloaded waiting in the ‘recents’ folder. A progress bar will briefly appear, followed by a pop-up that confirms that the snap has been successfully saved to your iPhone’s camera roll.
