far as I can tell, in the bx_posts_photos, remote_id is a hash of the file. Then the directory is the first character, then the first two characters, then the first three characters of the hash... and then the hash. to save database space and use when checking for duplicates? Because the photo isn't actually stored there. I have no idea where it is. Anyone know? I have tried finding the file name in the file system but it's not there.
