How do I extract images from my PDFs?

Image/figure extraction is disabled by default both in the Chrome Extension and Scholarcy Library web app. You can enable it in the Chrome Extension by choosing Options, and in the Library by choosing Settings, select the Import tab, and then sliding the Extract figures slider to the right.

You may need to experiment with both the v1 and v2 options for the Image engine setting (under Engine settings) to get the best results. Generally, the default v1 option works best for figures made up of a single bitmap, whereas v2 works well when each figure is made of multiple bitmaps or a mixture of bitmap and line drawings.
