Photos for Your One-Place Studies
The site mentioned on the hangout yesterday by +Kim Baldacchino and I as a resource for photos is: geograph.org.uk
There is also one for Ireland, which is geograph.ie
Then today I found yet another link: https://geolocation.ws/h/en/
I have a favorite photographer for my place in Northern Ireland and I found that while his photos are somewhat duplicated on the three sites, there are also different ones I had not seen on the third.
Also, the third link has some other options I did not see on the first two.
What is also nice is that they all supply you with copyright and reuse information, and will even apply an overlay to the photo before you download if you wish.
These are NOT just for the UK and Ireland, by the way.
