Wanted a way for images to refresh on dynamic collections to reflect their current content, so I schedule this script periodically. requires powershell core.   Notes set testmode to $false when tested take care to test on a backed up library - the script deletes primary images.. add a tag eg "cyclepic" to config.psd1 and library objects you want to have their primary image recalculated issues and suggestions welcome CyclePictures v0.0.0.1.zip
