I don't see why the photo would be dismissed as fake outright, without any analysis, and it's not what happens here. I would recommend caution when a 22-post account declares themselves an expert on this forum and asks you to "dude just trust me bro" on things like this.
Additionally, Magicalus, this style of posting is not acceptable here. If your post is not a sincere discussion of the Flat Earth Theory, it does not belong in the FET board. If you want to complain about how super right you are and how stinky FE'ers are, do so in the Angry Ranting board.
That said, your question is very non-specific. You want "an explanation for why the sun looks the way it does", which honestly gives us absolutely nothing to work with.
Please explain your argument (presumably in favour of RE?), and clarify what it is you'd like to discuss.
