i have around 40k photos. I wanted to start hand sorting them but thought to remove bad quality - overcompressed ones at first, so less sorting will be done.
The collection consists of a lot of photos collected for a long while from facebook and other social networks, mostly photos that relatives and friends used to post there, some old photos from school and college times, etc.
Then there are some part of funny/weird photos that we all use to send by email and other ways.
These were bigger part of sources, and there are are some other photos i found when i was scanning my old HDs
