They're just props in the tropical/beach-type picture this seems to be.
I have more, high quality res pictures. I either find them myself or people send them to me as an offering or reference material for requests. Pretty sweet deal.
I'm pretty picky. It really takes some good quality (or something special about the picture if it's not) to impress me. My collection is limited therefore, but the quality is assured.
I'm not saying it's not. In fact, the reason I'm able to be so selective is because I've seen so much and continue to. When I said quality, it wasn't meant to be mistaken for "good", as a lesser picture could still be as charming or moreso by it's own stand-alone merits. Rather, I meant that, for me, quality first decides the visual interest for me most of the time (the way people are naturally first attracted by a person's looks which lead to wanting to get to know them). As I analyze the picture, which happens in the first couple of seconds, the true beauty, other than the quality of the lineart, comes out.
And that is sometimes more rewarding than the quality itself.
