Thanks again for helping me troubleshoot this! You helped me meet a critical deadline when I couldn’t figure any other way. I had a bunch of rather large animated gifs across a Google Slides presentation, and it seemed to be choking the system. This method with pandoc and Revealjs seems to have no issues with image size, and, like you, I just hosted the images with imgur so I didn’t have to hassle with references outside my vault, figuring out where to stash the image folder, etc. Thanks a million!
