A publisher has accepted my memoir and at last contact I was told to gather photos too. What is the minimum dpi they would need for publication?
Is this not best answered by the publisher? Anyway, industry standard by a quick google said 300 DPI for covers. I don't know if that is what you mean or if you mean images as content for your book?
For content. As far as details from the publisher, I'm waiting to hear from the managing editor on that.
