Hi Keith, Yes, I've been transcluding the PDFs using Xavier's meta method, and it still crashes.
Also, it didn't occur to me to check if lazy loading was working by looking at the source. Thanks for the tip. But in fact my html includes the base64 PDFs. I tried looking at the source in Chrome and downloading a static copy, and I tried adding a [type[application/pdf]] in the natural place in the $:/core/save/lazy-images tiddler, but I always got gibberish.
