Whoa, slow down there! It's not that your images are bad, but I noticed that some of them show a content pack. We cannot have images uploaded to articles that use content packs. It's alright if you use them for yourself (like your user page), but not on our articles, with the exception of the Resource Pack article and its gallery.
(Sorry, just saw this now.) I totally forgot that I even had a content pack on! Super sorry about that! I don't even really use it much, so I'll keep this in mind the next time I plan on uploading a photo.
