Are we talking about the same photo? the one of the chameleon?
I don't think that photo is mundane at all. I thought it was striking and caught my attention immediately. In fact, I actually read the whole article because of it - whilst it wasn't the most beautifully written post in the world it certainly had me looking at the photo in a different light by the end of it.
Of course, if you were talking about the ones of the flowers at the bottom then I'd agree: they are dull and not necessary. In fact, I think the post would benefit from their removal - they detract from the story by not allowing the reader any room for imagination.
