In the latest beta of the upcoming iOS 12 update, Apple has included a feature that lets users generate iCloud links for sharing pictures via the stock Photos app.
The iCloud.com URL link option, first noticed by Reddit user Hunkir
The new sharing option appears in the bottom row of the iOS Share Sheet, and allows users with iCloud Photos enabled to copy an iCloud.com URL link to one or several selected images that lasts for 30 days.
Clicking a link in an email takes the recipient to a web page containing the image in question, as well as an option to download it. Sharing a link in the Messages app also shows a preview of the image right in the chat thread. The link also includes the author's name, the photo's title, and associated EXIF data, excluding location information.
The addition should come in handy for times when you quickly want to share an image from your iOS device, minus the hassle of uploading it to a third-party service. It's also more than likely that the iCloud link sharing option will feature in macOS Mojave.
