Note: This feature is only available on the Pro and Studio plans.
You (as the photographer) can download photos from your gallery while editing the gallery. You'll receive them as a zip file, and you can optionally apply a download preset to the photos, which will apply a size and watermark.
To download whichever photo(s) you have selected, select the photo(s) and click the "Download" button in the top bar of the "Photos" panel while editing a gallery. Alternatively, you can right-click on the image and select the "Download" button.
To select multiple photos, you can:
Click on one photo and then command-click on each other photo.
Click on one photo and then shift-click on another photo. This will select every photo between the first and last one.
In the "Download Images" modal, you can specify:
Which email you'd like to receive the download link to.
Which download preset (optional) you'd like to apply to the download.
