marking photos to make album from within the full view except form thumbs view only
Choosing photos from which an album will be made is only possible at the thumbnail view.
Choosing while in the full photo view is the way to go.
Choosing/marking in general for any purpose it may be (album making, deletions, whatever..) should be able to be done at the full view as well.
Thumbs view is more for orientation and navigation around the photos, serious work is always done at full view
