ARTstor has put up some terrific short video tutorials on YouTube to help with individual tasks. The video topics include An Overview of the new ARTstor site, How to Register, How to Make an Image Group, and How to Download Images to PowerPoint. They’re great for learning something new or just for a refresher.
The UC Berkeley Visual Resources Collection has also released a very helpful YouTube tutorial on batch downloads. On the same page there is a link to another video which helps navigate all the other image collections still available to the UC system through the CDL/Luna Imaging route.
