Artstor Offline Image Viewer (OIV)The OIV allows users to download much larger images from the Digital Library, at up to 3200 pixels on the long side. All Artstor users have access to this software, which may be used with any image in the Digital Library. Users may combine Artstor images with their own content to create digital slide show presentations that feature side-by-side comparisons, zooming and panning, and the ability to customize text on the slides. The OIV enables instructors to give classroom presentations using both high-resolution Artstor images and local content without being connected to the Internet.
