[Plugin: Amazon S3 Uploads] .htaccess rules

Hi, I have WordPress installed on Heroku (long story short, that means I can’t write to .htaccess).

This plugin works great, except that after the cron job runs, the images both on the front and the back end are dead. The images get to my Amazon bucket fine.

I’m assuming this is because my .htaccess is incorrect. Can someone tell me what rules I need in that file to get this working correctly?

Also relevant, I have WordPress configured with /wp-content/ and wp-config.php outside of the /wordpress/ directory.

My S3 URL is https://s3.amazonaws.com/Doulos/path-to-file.png
