how many people can you invite to a shared photo album?

Hi laxdad22,

Apple lays out the limitations of photo sharing limits in the following article, see the relevant section below:

• My Photo Stream and Shared Albums limits - Apple Support

"Shared Albums limits

These are the Shared Albums hourly and daily limits:

• Maximum number of photos and videos from a single contributor across all shared albums, per hour: 1000
• Maximum number of photos and videos from a single contributor across all shared albums, per day: 10,000

These sharing limits are separate from the upload limits above. For example, in the same day you could upload 10,000 photos to My Photo Stream, then share those 10,000 photos or 10,000 other photos.

Some additional limits for shared albums:

• Maximum shared albums an owner can share: 200
• Maximum shared albums a user can subscribe to: 200
• Maximum subscribers per shared album: 100 (the number of subscribers on each shared album)
• Maximum combined number of photos and videos from all contributors in any one shared album: 5000
• Maximum number of comments per photo or video in a shared album: 200 (a comment can be either a like or a text entry)
• Maximum characters per comment: 1024
• Maximum number of invites a shared album owner may send per day: 200"

Cheers!
