The whole process is pretty overwhelming at first, right? The trick is that there is not a really cheap way of being able to share photographs. I believe that most of the photo sharing sites require a monthly fee. You might want to ask some of the folks in the community how they are posting their photos under a different thread.
If you can arrange for a photo hosting carrier, it is very easy to share photos on-line. You can of course, also get your own website from a variety of places for as little as $5.00 per month - but again, setting it up can be a bit difficult for many.
