This tool scans for any screenshots (png only) associated with grd files and uploads them to Google Cloud Storage using upload_to_google_storage.py.

upload_to_google_storage.py is a tool that maintains content addressed files. It stores files with their sha1 hashes as filenames.

The storage bucket name used in the tool is tentative.
