"Today, with photo upload tools in Google Maps and our Local Guides program, we are providing easy ways for you to share your photos with an active and growing community. As such, we've decided to move forward with closing down Panoramio," informs Google. If you've linked your Panoramio account with a Google account, you'll be able to find your photos in Google Album Archive and they'll not use your storage quota. You can also export your photos in Google Takeout.
Google encourages Panoramio users to join the Local Guides program for Google Maps and share photos, add reviews and information about places. "It's all about that warm feeling you get from helping others discover new, enriching experiences. That, and the benefits. Every place you improve on Google Maps gets you closer to unlocking something new - from early access to new products to exclusive contests and events."
If you don't like Google's options, you can delete your Panoramio photos or go to Panoramio's settings page and delete your account.
Google acquired Panoramio in 2007. It was a Spanish startup which had a site that enabled "digital photographers to geolocate, store and organize their photographs and to view those photographs in Google Earth and Google Maps."
