Flickr

Flickr is an image hosting and video hosting website, web services suite, and online community created by Ludicorp and later acquired by Yahoo!. In addition to being a popular website for users to share and embed personal photographs, the service is widely used by bloggers to host images that they embed in blogs and social media. In September 2010, it reported that it was hosting more than 5 billion images. For mobile users, Flickr has an official app for iPhone, BlackBerry and for Windows Phone 7, but not for other mobile devices. Several third party apps offer alternatives such as flickr HD for the iPad.

Photobucket

Photobucket is an image hosting, video hosting, slideshow creation and photo sharing website. It was founded in 2003 by Alex Welch and Darren Crystal and received funding from Trinity Ventures.[2][3] It was acquired by Fox Interactive Media in 2007.

In December 2009, Fox's parent company, News Corp sold Photobucket to Seattle mobile imaging startup Ontela. Ontela then renamed itself Photobucket Inc. and continues to operate as Photobucket. [4]

In June 2010, Photobucket was named in the Lead411's Hottest Seattle Companies list.[5]

Photobucket is usually used for personal photographic albums, remote storage of avatars displayed on internet forums, and storage of videos. Photobucket's image hosting is often used for eBay, MySpace (from 2007–2009, a corporate cousin), Bebo, Neopets, and Facebook accounts, LiveJournals, Open Diarys, or other blogs, and message boards. Users may keep their albums private, allow password-protected guest access, or open them to the public.

Photobucket advertises 99.9% uptime, and offers 500MB free storage (reduced from 1GB on 19 August 2009). This reduction of storage space frustrated users, who were locked out of adding new images to their accounts unless they agreed to pay the upgrade fee. (Unlimited space with paid PRO account), Unlimited (was 100GB but went to 25GB in July 2008 and down to 10GB on August 19, 2009) monthly bandwidth.] Unlimited space and bandwidth is valid only for non-commercial use. Uploaded photos must either be smaller than 1 MB or 1024×768 in size (4000×3000 with paid account), uploaded videos must be five minutes or shorter (10 min with paid account).

Since Photobucket does not allow sexually explicit or objectionable content, they may remove content at their discretion due to violations of their TOS.

Photobucket supports FTP uploads, but the user must be a Pro account holder. Windows XP Publisher is supported as an alternative to FTP. It is available in free accounts.

Picasa

Picasa is an image organizer and image viewer for organizing and editing digital photos, plus an integrated photo-sharing website, originally created by Idealab in 2002 and owned by Google since 2004."Picasa" is a blend of the name of famed Spanish painter Pablo Picasso, the phrase mi casa for "my house", and "pic" for pictures (personalized art). In July 2004, Google acquired Picasa and began offering it as a free download.

Native applications for Windows XP, Windows Vista, Windows 7 and Mac OS X (Intel only) are available through Google Labs. For Linux, Google has bundled Wine with the Windows version to create an installation package rather than write a native Linux version, but this version is severely out of date (the latest Windows version, however, can be run with Wine, see Linux section). For Windows 98, Windows Me and Windows 2000, only an older version is available. There is also an iPhoto plugin or a stand-alone program for uploading photos available for Mac OS X 10.4 and later.
