Auto photo resizing in Linux

I still haven't found an optimal photo editing workflow that I'm happy with. I guess photo management varies wildly between people and it very much depends on the tools you're using, but for me it goes as follows:

  1. Take photos on camera.
  2. Transfer to my Ubuntu desktop to a temporary folder, e.g ~/Pictures/temp.
  3. Use DigiKam to quickly go through and delete non-keepers and make any minor edits as needed.
  4. Once ready, move the remaining keepers to my synced Google Drive folder.
  5. Select a small handful I want to share with friends/family, resize them to 1920p and email them out.
The process works mostly well, except I hate having to do the manual resizing at the end. So I setup an automated workaround hack for this last step:
  • Install Watcher and configure it to monitor my Google Drive sync folder.
  • Make it copy all new/edited images to ~/Pictures/_resized.
  • Have another watcher job that monitors ~/Pictures/_resized and converts every new image to 1080p.
This all happens dynamically in real-time with no user intervention on my part. So when it comes to step 5 to send emails, I can just browse the _resized folder and select whatever I need.

For anyone interested in going down this path, here's my watcher jobs.yml file:

  label: Resize images in _resize folder
  watch: /home/richard/Pictures/_resize
  exclude: []
  events: ['create', 'move_from']
  options: []
  recursive: true
  command: convert $filename -resize 1920x1028! -quality 90 $filename

  label: Move files to _resize folder
  watch: /home/richard/Google_Drive/SYNC
  exclude: []
  events: ['create', 'move_to', 'modify', 'attribute_change', 'write_close']
  options: []
  recursive: true
  # the --parents retains the same folder hierarchy structure in the destination
  command: cp -f --parents $filename /home/richard/Pictures/_resize/

I keep this file and the watcher installation in ~/.watcher/

And just run the job on system startup (add start).

There's a log file in the watcher dir, which can come in handy for debugging, but all in all, this works pretty well for me.
