Bulk Photo Uploader

We have a request to be able to upload a large number of photos.

Draft:

• ​http://haiti.sahanafoundation.org/prod/media/bulk_upload

• controllers/media.py
• views/media/bulk_upload.html

This work is in 3 stages:

Phase 1: Photos with Metadata

• Get it working so that files actually upload
  • media_image.name from filename= in POST
• Optional: Simplify the functionality so that it doesn't have any Geo aspects.

Phase 2: Geotagging

• For each photo uploaded:
  • Read the EXIF header in the files
    • Read the timestamp from the EXIF header
    • Create a record in the database with the filename & timestamp
    • If there's a Lat/Lon then include these fields too
  • Read associated GPX track & correlate timestamps to update the records
    • This is done already within ​JOSM, the ​OpenStreetMap editor.
      • ​AgPifoJ is a plugin which extends native functionality

Phase 3: Java or Flash widget

• To allow multi-select of files in the File | Open dialog (Javascript can't do this)
  • e.g. ​http://www.uploadify.com/
• ? UI to preview images in low-res to select which ones to upload
• Facebook is a good design model to look at - uses Java
