Photo storage sites?

I use my photobucket account as the main feed for my website. I wasn't thrilled with the limited storage capacity but it works very well. Since it was getting close to full capacity, I recently upgraded to the Pro Account for two years.

What I'm most impressed with are the daily / monthly statistics ... I can now tell at a glance which photos are popular and which are not, how many people look at my Shop Introduction Video, Before & After folders, etc. I really like it. It might not be worth it for non-commercial use, but I believe it was a well spent $38.
