img tags for thumbnails in part 2 of lab 8 are defaulting to display: none;

[jakehockey10]

I couldn't get things to work the way they are described in the second part of lab8, so I decided to just run the clone of the code here, and I'm still having an issue with the image thumbnails. If I go to Google Images and drag and drop any image into the app, I still only get a list item that has the uri as text. If I inspect element, and remove the display: none from the img tag, then I only get the PLACEHOLDER_IMAGE.

Can someone help me figure out why I'm seeing this behavior? Thanks!
