HTML support has now been added in a new version ( v1.12 ).
You can download a version from http://www.oik-plugins.co.uk
I will be writing a lot more documentation in the near future.
Using examples, it will show you how to use the format= parameter, which tells the nivo shortcode what data to display in the caption area.
It uses the code already built into the oik base plugin (v2.1) and which is already available to the [bw_pages] and [bw_cycle] shortcodes.
