Script to backup media (images) in a Twitter archive
#!/usr/bin/env python
# Given a Twitter archive, replace all references to Twitter hosted images with a downloaded local image.
# Usage: place in the directory of the Twitter export (at the same level as the index.html file) and run it.
# Note: doesn't work for video. Skips images that fail to download.
