The contests on this site are very confusing.  I just added a picture to a post that I had added to "my photos" last summer and submitted it to the contest only to be told by someone that I have done it wrong because it wasn't added to the playground as a picture.  Well when I tried to add it to the playground as a public photo it doesn't show up because it was uploaded last July so it is giving it that date in the playground.  I don't understand whey adding a photo to a post and submitting it that way can't be considered the same.  Please confirm.
