I'm new to this forum. My book has got some images in it and I notice there is a small download fee charged to me when book is downloaded. I'm just wondering if this download charge still applies when my book is downloaded for free during KDP Select free promotion. Or is it like a percentage so a percentage of nothing would be nothing?
Also, I'm thinking of trying to get a book made "perma-free" on Kindle Store in the future. In this case, would I be charged a fee for download (for example if it contains photos) or will it cost be nothing?
