Thank you Maryam (Wed 7/23)

We brought Maryam in this morning to attempt to help us understand the interaction between our code and the server as the images are retrieved. She told us how the browser communicates with the server, and that there is a simple check in Python, which would lead you to believe that there would be a similar check for a 404 error in JavaScript. We continued working on this, but still couldn't get the code to pick up the 404 error before the images have already been loaded.
