if you turn off photoi stream, then turn it back on, it should sync the 195 from your photostream.
you can currently wipe your whole photostream from the web interface for iCloud, you go into your account settings (which you do by clicking your name on the top of the main screen), view account, then click advanced. and you have 'Reset Photo Stream'.
not a 1 by 1 way, but something for now. This was discussed in the main thread about deleting photos from photostream in the iCloud subforum.
But if I only want the 135 pics that are in my album to be backed up will turning the stream off and then back on do that?
