I’ve been playing with the standard WordPress Twenty-Twelve theme and a variation based on Zurb Foundation, WP-Forge.
I played with some logo alternatives and manually entered the “Rx” graphic on the how-to post titles. It’s simple to do. In the title box, add your image location as:
<img src=”http://www.something.com/Rx_blue.png”> The is My Post Title
This is My Post Title
It looked a bit ugly in the WP dashboard because the “<img etc…” code/title pops up in all the post title listings. I’m just going to add [Rx] as text in the title. Simpler.
