title: Collapse in Bootstrap 3 delaying on click even after changing transition timing
body: <p>There's a bootply with an example here: <a href="http://www.bootply.com/29mKfY3Vnf#" rel="nofollow noreferrer">http://www.bootply.com/29mKfY3Vnf#</a></p>
  
  <p>I'm trying to work with a collapsing function in Bootstrap, and everytime I click on the speaker header to expand the collapse, there is a short delay, and then the image appears and shifts the text down. I want to make this smoother. I think that the image is already loaded. I've tried changing the timing to a small number to approximate no transition(according to <a href="https://stackoverflow.com/questions/13119906/turning-off-twitter-bootstrap-navbar-transition-animation/13829926#13829926">this</a> thread), but it doesn't seem to stick. Any idea what I could do? Much appreciation.</p>
