### AI overview

A tutorial explains how to regenerate Shotwell thumbnails for photos modified after import, limiting the operation to images from the last month and noting that ImageMagick must be installed.

### Source excerpt

I love Shotwell external link for it's simplicity and easy export to Piwigo external link . After Christmas I added new photos to my library but after that I made some modifications to them (red eye reduction, etc...). Because Shotwell generate thumbnails only on import, all my modifications were not visible on preview.
