So I have a bunch of gifs saved in my Research folder, but unfortunately, when I click on them, they don't play - I have to open them in an external editor to view them. Is there a way to make them play directly inside of Scrivener?
I've looked through a few sites and discussions such as this one or this one or this one - but none of them describe your scenario and there is no mention of this being possible. Funny thing: your question here pops up first in Google for me when I search for "scrivener gif". There doesn't seem to be a lot of interest in the subject and no available documentation that would indicate something like this, which is why I conclude that the answer to your question "Is there a way to make them play directly inside of Scrivener?" is simply "No", no matter where you want to play the gif exactly in scrivener.
