Image size/resolution for Kindle page?

I missed this post. That is very good to know. I'll have to look into that because it changes everything. I was under the impression that it was 15 cents per MB, period.

I have, and yes I'm happy with the results. Even the images uploaded at the old recommended size of 450x550 pixels are acceptable on my Fire tablet and Paperwhite e-inker. Now however I upload images 800 pixels wide, though compressed to the recommended 127 KB. That's meant as a courtesy to the clueless owner of a hi-rez device who doesn't realize he can zoom a smaller image (and those images uploaded at the recommended size of 600 pixels wide can look pretty small on the newer screens).

And check out the screen rez's. You should not use 72dpi. You'll be sorry, if you see your book on an HD device, or even a plain Fire. Scroll down past the screen sizes, and look at the density. The lowest-density screen is 149ppi, and the larger go up to 339ppi.

My assumption in giving this advice is that your images are really important to you--that they are more than just, say, a chapter head image, or something along those lines. If they are NOT crucial--say, they are chapter head images, or a fleuron, or the like--you can go down in rez and overall size.

BEAR IN MIND that a) the K4iOS app still doesn't handle image sizing very well, for images under 100% of the width of the screen, and that b) the LITB is now showing ebooks pretty much as they are coded--so, an image that you've set to be 80% of the width of a Fire, is going to need enough rez/pix, etc., to look halfway decent in the LookInside when the viewer is a looking at it on a largish desktop monitor--like mine. Right? Publishers and professional book producers need to think multi-dimensionally these days.

Hope that helps.
