One of my very favorite photography sites to visit is
MCP Actions Blog. Jodi posts TONS of useful photography information and tips. (She also sells Photoshop actions that are high on my want list, but I need to calibrate my monitor before I spend more $$ on anything else.)
As I read through her blog I found a recent post on creating what she calls "Branding Bars" as another way to watermark your photos. I like the look that it gives to photos I've seen with it, so I decided to try it out. I LOVE the extra color that it adds to my blog. Of course, I also had to make a new watermark to fit nicely in my side branding bar.
