Just a few observations. 1.No explianation of what the secret URL is. I uploaded a photo and was unable to add tags straight away. Confused I went to My Photos but was told I needed to login "Hmm I don't have an account...", so I put my email addess into the forgotten section just to see what happens and got an email (In which the link wasn't clickable) from which I pasted in the URL. Then I was in "My Photos" and could edit and tag my existing stuff. But... 2.Users are able to upload photos under the guise of other users?!? Seems that even though I now have an "account", anyone can just use my email address and upload photos into my area. I opened up a different browser and could upload photos without it asking me to authenticate my "account". 3. Seens "My Photos" is just a link to the login section, until I specifically go to "My Settings" and set a password. No where is this clear. I think it's getting there, but needs a lot more work when it comes to directing users with what to do next. A lot of people who would be using this service will have little clue as to what to do next.
