But there's more to photography online that just posting up your snaps. We've rounded up eight websites that allow you to enjoy photography on the internet.
New York Public Library Digital Gallery
There are plenty of one-of-a-kind film prints floating around out there in the non-digital world; luckily, many of them are in the collections of public libraries and museums.
Many of these institutions have taken on the formidable task of scanning and publishing those collections online. One great example is the New York Public Library Digital Gallery.
Launched in 2005, the NYPL scanning project has created a searchable online database of photographs - as well as maps, rare books, posters, and other gems - from its collection.
Though huge, the online collection is amazingly only a sliver of the NYPL's total holdings, with more files being added every day.
You can search the 700,000 images by keyword or browse by category; you can also browse by department or check out the library's Flickr feed.
The scans are mostly 72dpi images, but high-res prints are available for purchase. You don't even need to be a member of the library.
Multicolr Search Lab
Good photographs are about more than their subjects. So it makes sense to organise them by something other than keywords.
As the name implies, the Mulitcolr Search Lab from Idee Inc lets you look for photos by colour.
You can select up to 10 different colours from a palette - even the same colour multiple times to increase its presence - and Multicolr searches over 10 million Creative Commons images on Flickr.
A collage of thumbnails is updated immediately after each selection is made. Click on an image and its Flickr page will open up in a new tab.
Multicolr is particularly useful for designers and photographers who are looking for a specific shade in an image, or just a splash of inspiration.
There's been a surge in image-based social bookmarking sites in recent years.
FFFFOUND! was one of the first, but you'll either have to wait for an invitation or be content with just browsing (which is satisfying enough).
There is a less exclusive alternative: vi.sualize.us.
Sign up for a free account and download the browser plug-in.
Then, when you come across an image anywhere online that strikes you, right-click and select Add Image to vi.sualize.us, and type in a few tags for organisational purposes.
When you're not saving images for inspiration, you can spend hours following all kinds of visual tangents in other community members' collections.
