Self-voting is frowned upon because a person typically shouldn't be the judge of one's own work. Why and Whether a self-vote causes a curator to not vote your post depends on each person who votes. I cannot answer why these tags are banned for I never banned them. I never used the phrase "post photos directly", can you quote me instead?
Did you mean this?:
Photos help bring attention of the reader to your post. You can use photos of your own creation, screen shots, or stock images. You can copy your images to the 'clipboard' in Linux or Windows, and paste them right in the editor. You can take photos and drag and drop them into the editor window.
You can click in the editor window and paste and the photos get uploaded and appears in the text as if it's some kind of local word processor. You can do that.
Your curator reward goes to your wallet. You can sell, stake, give away. More detail on staking is better for another article. It's yours to do as you please. You get rewards for voting posts. The more stake you have, the stronger your vote but you also get curation rewards for voting on the content that will become popular. If an investor is going to buy POB, it might be better to buy now rather than down the road because it is going to get more scarce as time goes on. I cannot guarantee that POB will stand the test of time, but I am going to make some efforts that will help make Proof of Brain stand out from the other tribes.
