I am trying to find a way to add more blog post content to the activity feed. I have a photography class where each student posts multiple photos inside of a post on their blog. What I need is a way for the activity page to show all of the pictures the student has posted in their latest post. The only thing I get is the first picture of the set they have uploaded. Is there a way to customize the bp_excerpt call or get rid of the excerpt all together and display all of the content?

Thanks
