The Photo Dropper Plugin I recently mentioned has been cool to play with, but I was tired of hand coding my HTML when I needed something to stand out and blockquote wasn’t appropriate to use so I poked around the plugin directory and found a plugin called WP Attention Boxes that did exactly what I wanted. One click and the code for the call out box is dropped into your post, you just add whatever text and images you need to appear in the box. You can use their defaults or you can customize the box colors to match your site’s theme.
Here’s an example of how I used the plugin at The Small Business Transcriptionist:
You can get the plugin by searching for WP Attention Boxes from your Add Plugin page of the Dashboard or you can find it directly to the plugin directory at http://wordpress.org/extend/plugins/wp-attention-boxes/
Hopefully that saves you some time coding boxes and stylizing your blog posts
