Geograph - photograph every grid square

In the line of links just below the credit line on the photo page are one or two yellow 'thumbs up' icons. Just one, which says [👍🏻 Like] if there is no description. Or one saying [👍🏻 Like Image] and another with [👍🏻 Like Description]. You can also find the 'Like' thumbs on the 'Full listing + Links' format of the photo search under 'Thumb'.
Click on one or both to show your appreciation.
When this happens to one of your photos, it is reported on the section of your profile 'Use of my photos around the site'.
