I’m trying to put my cover image file into my front matter, but no matter what I do it won’t let me. Having said that I can paste into a file. But in all the tutorials I’ve seen the cover image is definitely in the front matter freestanding. I’m probably being a bit thick, but what is the answer?

For ebook outputs, there’s a separate section for the cover image in the compile window (only appears when you select epub or kindle). Otherwise, it’s my understanding that you do have to add the image to a regular text document to use it in the front matter (or the draft) folder. That’s the only way to add a cover image to a PDF, .doc, or other outputs.
