Add a Cover Image to a PDF Using Calibre
One of the things I hate about making files for my readers to download on their Kindle Fire tablets is that they look awful! For some reason, Kindle doesn’t take the first page of the PDF (or MOBI file) and make it the default cover — the way iOS handles it. Nah, they just give you a generic, white file icon, with the beginning of the filename, written unceremoniously across it.
Luckily, there’s a snazzy workaround.
