Staff Bio page layout suggestions

Hi!  I'm trying to update our staff page on my school's website.  Right now, we've just got photos and I'd like to add a bio for each staff member as well.  Ideally, I'd like to be able to click the picture and have the bio pop up and collapse without redirecting to a new page. 

I've tried creating a gallery and enabling the image description, but there are a lot of limitations there that don't really work for me.  I don't really like the lightbox feature because it makes the picture bigger, which I'm not a fan of.  Also, you only see the bio if you mouse over the image.  I feel people would miss the bio if they didn't know they had to mouse over for it.  

I have version 7.0 and we are using the Mentor Template.

Does anyone have any suggestions on a fairly simple way to create what I'm looking for?  

Thanks!

You try consider using Accordion block to do this.
