ePhotos is a free Applecscript App that provides back the automatic file resizing iPhoto had when sharing photos to email clients before it was removed in Apple Photos. The script takes the selection of photos within Apple Photos and resizes them to three different sizes. Once the size option is selected ePhotos then creates a new email in your default email client and attaches the photos. This is non destructive and the script does not place the photos as an inline attachment.
Note: this script is only compatible with Postbox and Microsoft Outlook. Some initial user setup is required when first installing the script, but then it's all automatic. Please read the Readme doc for full installation instructions.
Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.
