Upload and converting pictures automatically from Dropbox
I’ve been using Pelican to publish this website for awhile now, and one of the things I wanted to do was to be able to post from my phone and include pictures. To accomplish this I wrote a script that checks the upload folder in dropbox, and if there is a file, it will re-size the pictures to 4 different sizes and upload it to Amazon S3. I can then easily link to any of the sizes of pictures for my posts.

This requires ImageMagick to be installed for the convert command. Once I have the script written I set up crontab to run the script every minute.
