I learned about Photobucket just the other day. What you are seeing here is the result of spending about 5 minutes at the site. The pictures are simply digital photos of Bonnie and Skipper (our two Shelties) that I already had on hand.
How do I intend to use Photobucket? When I have a number of pictures I want to post on a blog, that series of pictures posted to Blogger can encompass quite a bit of real estate. By posting the photos to Photobucket and putting them together in a slide show, I can show quite a few pictures in a limited amount of space. Here is a an example that I used on our school system blog.
A Photobucket account is free.
