What you have provided as the Image URLs are not image file URLs.
For example, focussing specifically on "FOOD GLORIOUS FOOD" you provided http://oswaldsoutlook.com/2013/02/21/wi-in-the-spotlight/itv-group/#main
This is a page with an image on it, but it's not an image URL.
The image URL is http://oswaldsoutlook.files.wordpress.com/2013/02/itv-group.jpg
To get that, click on that page where it states the image dimensions, "5060 × 3373" in this case.
The same issue is true for the other broken Image widgets.
