freezeframe.js should have a method to refresh calculations of DOM element

[eballeste]

depending on user's viewport width, an asset that might be originally hidden from viewport, the freezeframe script will give it a width and height of 0. it would be great to be able to call some type of refresh method that correctly calculates the images dimensions if it ever becomes visible due to browser resizing.

I am having the same issue. Some of my GIFs are originally hidden, and thus they get an incorrect width and height.
