Prevent Image from being Removed upon Close

[executives]

I noticed when I close the Lightbox Modal on a single image, that image gets removed before the modal goes away. This produces an abrupt resize of the modal since there is no image to expand the modal's dimensions, moments before the modal disappears.

I'm using a local copy of angular-bootstrap-lightbox.js ver 0.12.0
Commenting out line 692 resize(); seems to fix the issue for now.
