I just released the second bamboo plugin: Photo!
It's a port of the previous photo-album plugin, I changed the syntax to be XML compatible, and the plugin now works at the middleware level.
Crap, I should have started my K-on project. I was extremely annoyed when I found that the current bamboo does not have this photo plugin capability, so here it is, another sleepless night.
The photo plugin, as the highlighting plugin, also uses the HXT library. Despite the complexity of HXT, I think it's a fairly good library: The abstraction is beautiful and working with it is a pleasure, though there was a steep learning curve for using the arrow abstraction.
Example:
< plugin
type="photo"
name="09-07-05 Project K on"
/>
