Finding the right site to upload and share photos for promotion purposes can be key to interesting couples in your work. Facebook is a great way to draw the initial interest from people, but it lacks capabilities that Flickr has had for years according to Laurie’s article on PhotoPreneur.
Flickr is set up in a way that number one, protects your pictures. Next it is community based which means anyone can find your pictures. And probably the most important thing of all is that Flickr is set up a way that encourages photo sales. You may just want to think again before setting facebook as your only social media photo site and make sure you know what you will be using it for.
