Im not a fan of the across the centre of the image style, I think unless you are super-pro and already making a good living off it you aren't going to impress people by hampering their viewing pleasure.
I have people occasionally nick photos and use them on websites, which im not overly happy about, but anyone who ever would pay or in some way compensate me, does. I would never charge someone to use an image for non-profit reasons, if they ask and I approve of it. Having said that, if they dont ask, they can pay.
Yours is a bit hard to see but if thats what you are going for, cool. Not sure thats quite how you spell photo though
I did use my oO logo but now use my website name since so many of my photos get linked around no link to my site. So people at least have a way to find me.
