Photo-sharing sites usually provide an option to order physical prints of your photos. A third party might provide the service, or the sharing site itself might provide it. Depending on which site you're using, many options are available. You can have the photos shipped directly to your house, though you might have to pay shipping costs. Some sites affiliate with "brick and mortar" stores. You can find a location close to where you live, and you can just drop by the store to pick up your photos.
Other options allow you to customize your photos before they are printed. Add a border to give the photo an easy matte, or insert some text and clip art and make your own Christmas cards. There's also a wide range or prices for digital photo printing. Many sites offer special deals with prices as low as six cents per print, or a certain number of free prints when you first create your account. Regular prices generally fall in the 12 to 20 cents per print range.
While most photo-sharing sites are free, many also offer premium memberships for a monthly or annual fee. This opens up more advanced features for users and removes some of the limits placed on free users. For example, sites may limit the upload bandwidth of free users. Premium members will have either no limits, or much higher limits. Premium members also view the site ad-free, while pages viewed by free users may have banner ads on them. Access to full-size, full-resolution versions of images may be restricted to premium members as well, and they may have their own personal URL on the site (such as http://www.photosite.com/edsphotos or http://edsphotos.photosite.com). The exact features available to paying site members depends on the site.
