Earlier in the school year ArtStor made a minor change: Users wishing to save pictures from the ArtStor database must now log in to their user account. Thankfully, creating an account and logging in to it is very easy. There is a prompt in the upper right-hand corner of the ArtStor main page, immediately visible after a user enters the digital art library:
Registering must be done from an SPS networked computer. Following this, users may then access their ArtStor account from off the grounds.
ArtStor has written more detailed instructions about registering for an account HERE.
