Content creation

I've been trying to create a timeline. It's a great idea, but I'm not able to get it working 100%. The timeline underneight the content is not showing correctly. Is there something I've done wrongly?

Another thing is the images, it seems as though you're only allowed to hotlink images from wiki and a couple of other places, not upload you own, or is there something I've misunderstood?

I've been playing around with h5p on my site, and it works really well with wordpress. 

Primaraly I've been using the hot-spots, like here: http://oljenytt.no/?nessio_gl=tofasestromning
