Well, it is. For some formats, including epubs and PDFs, it renders the first page and uses that. For kepubs, it looks for the image that has been marked as a cover and uses that.

and the epub thumbnail was resized appropriately before sending by the calibre kobo driver.
Which it can be. The KoboTouch driver generates and sends the three sizes needed by the device. And if you resend a book, it removes the existing covers so that they can be regenerated by the device, or the driver.
Quote:
are the thumbnails actually stored on disk as well? can you just drop them and have the device pull it from the epub?
And if the device generates the covers, they are saved for later use. Look in the .kobo-images directory on the device.
