Flickr v. Facebook
Many people know that Flickr is an outstanding place to share personal photos. But, researchers and bloggers also use Flickr to host images. Photo sharing is Flicker's main purpose and as such offers easy access to image editing and printing. It has a sophisticated system of organization. Users can access photos without having an account. In August, 2011, Flickr reported over 6 billion images being uploaded daily. That's a vast inventory for users to browse. In order to upload images, though, the user needs to register. From photographer's perspective, Flickr's image quality is lower than competitor's photo hosting/ sharing and the quality of the comments on Flickr are poor. Some say photos on Flickr are in the old, style square format and appear with ugly black lines on either side of the photo. Other's insist that with all the changes happening in Flickr, it's just a confusing mess. But, still, Flickr is one of the most popular sites for photographers and photo sharing.

Users can upload photos to Facebook, too. It's the biggest and largest social network. Perhaps because it's not a photo sharing site, per se, it's image quality is low. Facebook compresses uploaded images, which causes color banding and the noise is amplified. However, because it is the biggest and largest social network, many photographers are still uploading images onto Facebook for the purpose of attracting clients. Photographers can read a huge audience. Also, the comments are more casual and feel more like a discussion on Facebook.
Photo sharing benefits libraries:
Libraries can utilize photo sharing networks to better serve their patrons. With photo sharing networks, libraries can collect and organize images into tasks or groups and can easily share and create. Images can be easily uploaded onto blogs and websites. Image resolution and size can be adjusted without owning photo editing software.
In addressing reference needs, librarians can use Flickr to take a hi quality photo of an older image and/or text and other patrons can have access to it. Slides shows can be created and embedded into blogs or website. Photos can be shared of the library, community events, etc. and used to encourage participation and interest. Photo sharing networks can be used to create slides used for tutorials and staff training as well.
IUPUI uses photos in Twitter to encourage interest in the campus:
Photo sharing is an important part of community building. Photographers can attract clients, businesses and organizations can encourage customers and patrons, and friends can simply share important moments.
