EXIF parsing for Images about mediacrawler

[ctengel]

Fields:

• Camera
  • Image Make
  • Image Model
• When
  • Image DateTime
  • EXIF DateTimeOriginal
• Resolution
  • EXIF ExifImageWidth
  • EXIF ExifImageLength
• Orientation
  • Image Orientation
• Thumbnail (strip! - it's huge sometimes; perhaps utilize later to do a quick compare)
  • JPEGThumbnail

Notably still need to:

• Find latitude/longitude
• Understand if/how to apply orientation
• Decide if using EXIF for reolution makes sense
• Decide if/how to deal with Unix mtime vs timezoneless times here
