Something is wrong with my post font.

I am not sure if I am in the right place with my question, but I have to try. Today when I entered my website to make couple of changes in my blogs I noticed that they look differently. There was no pictures on any of them and the font looked as HTML. Moreover, instead of picture there was a strange code that I have not seen before. It looked like this:
<p><img class=”alignleft size-medium wp-image-221″ title=”Russian angel” src=”http://www.russiansnowangel.com/wp-content/uploads/2011/11/1-1-e1320761554364-274×300.jpg&#8221; alt=”” width=”274″ height=”300″ />

Please help!
