Though this thread is old, I've decided to add my post. I also was one of those people who shared photos only with family members and friends. But nowadays there exist such inspiring websites like flickr or vimeo, and I decided to build my own site. It has to be noted, as the demand for the website builders has increased, they have become easier-to-use. Personally I used one of the
photography website builders and didn't face any issues, though I had no experience. I should say, photography websites help not only to share your images, but also find clients and sell your works, of course, if you want to do this.
