Images keep showing up as broken

My website https://www.techin5.com is hosted on wordpress, so I believe this is a wordpress issue.

Anytime I upload files throught the wordpress upload image option, and I insert the image in the post, it appears broken. However when I copy and paste that image in, it doesnt appear broken, but rather it comes up how it is supposed to. Unfortunately this means my featured image is broken permanently.

It’s not an image problem, because the featured image actually appears on my facebook fan page (which is linked to my site), so clearly something is wrong on wordpress, but what could it be?

This is happening for my latest post
