Dozens of Amazon CDN images appearing in my test results???

Does anyone know what this is??

My WordPress blog https://www.allthingsdemocrat.com was loading quickly just yesterday at webpagetest.org, pingdom and other online test sites. But tonight, its taking up to 20 seconds to load the home page in webpagetest.org with many image files taking a long time to connect. And something very strange is happening: I show dozens of images from an Amazon CDN appearing at the end of the test results that add several seconds to the page load, however I don’t have anything to do with those images and don’t understand where they came from, I don’t use an Amazon CDN and those images don’t appear on my site at all – please see this results link to see what I mean: https://www.webpagetest.org/result/140504_JR_590/1/details/.

Every line in the results from 199 to 336 has nothing to do with my site. I don’t know why it’s there! The line above it is the Raw Story video player; could it be inserting all that garbage???

Can anyone tell me what’s happening? Thanks!
