There's a bootply with an example here: http://www.bootply.com/29mKfY3Vnf#
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 this thread), but it doesn't seem to stick. Any idea what I could do? Much appreciation.
