When you share your album people can comment or like your photos and videos. You can disable this in two ways.
Disable comments for one album
Open the album and click on the three dots top right. Choose 'settings...'. Uncheck 'Allow comments'
Disable comments for all your albums
Open your profile and select 'settings' (you can find your profile by clicking on your avatar top right). Then uncheck 'allow comments'. Now this feature will be disabled for all the new albums you create. If you want to disable this feature for all your albums (also the existing ones) then click the link 'apply these settings to all my albums'.
