Incoming Slide Suddenly Changes Size

This plugin behaves differently on different browsers. That said, I don’t seem to be able to prevent the incoming slide image from going through its animated transitions from about 0.2 – 0.8 (20%-80%) its original size then suddenly jumping to full size on the last frame. This sudden size jump causes all of the content below the image to jump and jerk and shift position on the page making reading the page below the slides difficult, if not impossible. Clearing the browser cache will clear the problem temporarily but it comes back if visiting a different page with the same plugin active.
