Slide preview images #8
Description
Currently, on the slides page, we show the raw slide code rendered inside each slide card. Ideally we show what the card will look like. It's too expensive to render every slide inside each card, so we should just show a small preview image.
We can achieve this by taking a screenshot of each card preview on save and storing the png alongside the card itself.
Probably the nicest interface for doing this currently is via nightmare.
