Images breaking post

Hi.

I am using the theme “motion” by 85ideas.

on this page …

http://cutjapan.com/drama/go/

every time i try to add an image above the one with the caption “death” …

the page contents breaks.

so what I mean is that if I add another image above the aforementioned one, and update, then view the page, the sidebar – footer – header – list of tags at the bottom … all appear, however the post contents disappears and the only way to reveal it again is to take out the image #3 i inserted.

any ideas on what could be happening.

all other pages work without a hitch.

thanks so much.
