Online Photo Services

I have spent some time this summer trying to find an online photo service that I am entirely happy with. Let me share some of the pros and cons of what I found:
Snapfish
I have used this site for about a year for getting photos printed. I have been really impressed by the quality of printed photos and the seemingly unlimited storage space for photos. However, the sharing options are far from adequate, and I can't seem to find a way to tag photos. It was for this reason that I tried to find an alternative.

Oosah
Oosah was the next site I tried, tempted by the promise of 1TB of online storage space. It all seemed promising at first, but then I realised that I couldn't upload documents as well, meaning that I was never likely to come close to using all of the 1TB. Unfortunately I can't print photos from the site, and, as clear as day there were pornographic photos in the public photostream! Not ideal.

Picasa
This was next on my list. This could be useful as it links with Blogger. However, I can't print photos from the site.

Facebook
This is really useful if you want to share photos with friends, and the ability to tag people in photos is brilliant. But what if I don't want to share the photos, or simply back them up? Facebook wouldn't allow this.

Flickr
Flickr appears to be one of the best photo sites around. The tagging is excellent, and the photostream and ability to link directly to individual photos are all valuable features. I can edit photos online, and make photos public, for sharing, and private, just for backing up pictures. However, there is one flaw - at the moment you cannot print photos in the UK directly from Flickr.

Photobox
This morning I am trying out Photobox. Despite rather slow uploading speeds, so far it looks the most promising of them all - photo sharing, making photos private, tagging and printing all seem possible. Could I have found The One?

Anyone got any thoughts?
