Jus tried, once images are uploaded to an album u can't add more photos to the same album. This means any album u make will have a min of 5 to a max of 10 images.
Hence main aim of using album is for the convenience of doing a batch upload.
Does it means any photos I uploaded into Olympusphere can't be deleted in the future? What if the T&C of the site change in the future?
Also not able to move and add photos to an album is a bumper.
