I think what may have happened is that I have been working on creating a new function, being able to send a photo to the Forestry Forum by email. I had a temporary directory I was working with that I was testing with. Rather than creating your own album, you probably uploaded the photo into my test folder called mobile uploads. I created and deleted that album several times during the evening and late into the night, and if that is the album you chose to put photos in, they would have been deleted.
