i need to display current status of a document approval workflow task in asp.net web page with a specific activity highlighted.

i have seen the visual workflow tracker example (in wf&wcf samples) but i have two issues,

1-i have to render workflow in asp.net not in a wpf app.
2-i don't need to display current status with workflow running, all activities that need to highlighted are the one that require user input. e.g. "waiting for approval from department head" etc. 

if i could just convert the workflow xaml to jpg after highlighting a specific activity by activity id that created a bookmark and waiting to resume the bookmark it would do the work.
