Images not showing

Hi,
I’m trying to get images displaying on wordpress 4.1 and it seems to not be working.
I even tried to paste your shortcode structure (just like your example) but only changing the rss source.

As the result I get the html tag printed as text <img src="thepathtoimage"/>

I think that simplepie is failing to load.

Thanks
