Ocular Professor (OP) is a WordPress theme designed expressly for photobloggers. OP is the evolution of Professor, a theme designed to showcase written content that wound up being used predominantly for photoblogs. Because of its focus on text, Professor had a number of shortcomings when it came to displaying photos. With the release of embedded galleries in WordPress 2.5, Ocular Professor was born (or branched, as the case may be).
OP was designed and tested with WordPress 2.6, and I’d recommend upgrading if you aren’t already running it (not only for security reasons, but for the improved image handling and gallery support). OP has been tested with Firefox, Safari, Camino, Opera, and Internet Explorer 7 on both OS X and Windows XP. Internet Explorer 6 has not been tested, nor are there any plans to do so.
