Thanks for the suggestion. There's no way we can do that currently because it requires some PHP libraries that aren't guaranteed to be on all servers (ImageMagick and GhostScript). There are some code examples here if you wanted to give it a try: https://www.google.ca/search?q=PHP+Create+Thumbnail+from+PDF
And if you had a client project with the budget for it and a server that supported those libraries we could always look at doing it as a consulting job for you.
In any case, thanks for the suggestion!
