Here are a couple of pictures I took in the last week that I like, and have attempted to watermark.
I don't know, I'm thinking the watermark needs to be bigger to be effective (and not easily cropped off), but I don't really want to detract from the picture, because then I'm less apt to post pictures at all. I personally hate looking through large watermarks on photos, because my eye (and brain) is then drawn more to the words than the image.
