Yes, just simply state that these photos were taken by you and are owned by you, but there are two on here that have shown up on multiple sites, so those were too similar to images already being used, and someone could look and say there is plagiarizing going on; all I'm recommending is even if they're yours, in order to avoid any problems, just state so; we do it for safety and convenience so there is no question.
And, as a side note, you can edit these posts to make changes or correct typos, just for info.
Now, go have fun, onward and upward!!!
