If you want to find images that are being shared right now on social media you might want to take a look at EyeIn. It's a fairly straightforward search engine - it's just that it pulls data in the form of images from social media platforms, and not the web. I tried a search for UK Houses of Parliament and got back a location and some event and trending information. Virtually all of the event and trending information was wrong, but the location was helpful, since you can click on it and expand to view the images that are being taken in that location at the moment:
You can look at individual pictures or run them as a slideshow. It's quite hypnotic to look at a lot of pictures that have been taken in pretty much the same place at the same time - I'm pretty sure that I saw photographers of one picture appearing in the background of another one!
You can also follow up the trending topics as well. I looked at the sad case of Charleston and as well as the images from the location people were sharing image tweets that were also included. There were links to major news stories as well.
EyeIn allows you to limit your search to 'now', yesterday, last week, last month, last year or a custom date. It's fairly basic and what you would expect for something only just out of beta, but it's a useful tool to see what is happening in one specific place. For my money, that's what it's most useful for - when you have a location you can increase/decrease it or move from one place to another - I quickly moved from the Houses of Parliament down the road to Buckingham Palace for example.
How long it's going to stay in business is another matter entirely. While it's conforming to the requirements of Twitter and Facebook, they could choose to turn that tap off at any point. So make the most of it while it's there!
