Steps to Reproduce:

1. Start up portal
2. Add a blogs entry
3. While adding a blogs entry, scroll down to add a small image
4. Click on the "Select File" button and move it around

Expected Results:
The "Select File" button probably shouldn't be registered as an image that a user can drag and drop into the Drag and Drop uploader.

Actual Results:
Please see attached screen capture. No errors appear on the console, and refreshing the page will clear the Drag and Drop instance.
