Just for fun really, suspect no one would want to use it.. But if it works for that as well so be it. This type of watermark is quite useless to be honest, it can be removed in the flick of a wrist. If serious about wanting to secure (copyright) photos this is not how you would do it. I just like my name on my pictures (except the ones I scrap, kind of weird I guess). Started doing this when I joined a couple of facebook photo sites.
