[Plugin: WooTumblog] No images, videos showing up

I’ve just installed WooTumblog at https://karlomarcelo.com and posted two posts to test it.

The text of the “posts” are showing up fine, but not videos.
See https://karlomarcelo.com/2012/07/belarus-color-guard/

And for some inexplicable reason, an image published appears not in the post but over in the sidebar!

Help!
