With GraphicConverter installed on your Mac, here’s how you fix a given folder. It’s a superb piece of shareware, well worth the registration fee, and I’ve been using it daily for years.
Sometimes Mac OS X seems to automatically generate preview thumbnail icons for images, but other times there’s no preview associated with a given file so you get the generic icon instead.įortunately, it’s really easy to update a generic JPEG icon to be a preview image instead using the splendid GraphicConverter program that’s probably already on your computer. This is a bit of a mystery to me too, I have to admit.
