I'm looking for some advice on image sizes for donated books. I'm also thinking of submitting a corrected version of a book I recently submitted and I could use some guidance on that too. I have been using RST for all my submissions, and my latest submission was this one: https://www.gutenberg.org/ebooks/62549 This is my first attempt at an RST book with illustrations. I think the web page turned out pretty well, but when you read the book on a Kindle it is a different story. The illustrations are all 300 DPI and other than some rotation and cleaning up are the same size as was in the original PDF from Google Books. I specified that the illustrations should be displayed at 50% of the screen width, which looks nice in a web page but like postage stamps in the Kindle. The other thing I'm concerned about is the amount of disk space the image files take up. I'm thinking I would have been better off to display the pictures at 75% width or higher, and to use a Linux utility called "mogrify" to do a bulk resize on them to get the disk space usage down. I've got another book in the pipeline: https://www.google.com/books/edition/Aeroplane_construction_and_operation/e-FBAQAAIAAJ?hl=en&gbpv=1&dq=aeroplane+construction&pg=PA7&printsec=frontcover This is a terrific book from 1918 called *Aeroplane Construction and Operation*. It is lavishly illustrated with photos and diagrams, and those images are a significant part of the value of the book. Having said that, the zipped up RST + image files is a hefty 98 mb. You can side load something that size into a Kindle or Nook, but you can't email it. I plan to keep a copy of the 300DPI files so I can make a print on demand version of this book, but I'm willing to bulk resize the images to a smaller size for PG. The question is what a good size would be? Thanks. James Simmons
If the submission is fairly recent, it’s best to contact the WWer who handled it (in 62549’s case, that would be me). If the only changes are to the RST file itself, probably all you’ll be asked to do is send the revised file as an attachment. I can’t speak to image sizes. A submission of that size may not be common, but it’s not unheard of. I’ve seen a few considerably larger.

Al, I'm going to experiment with image sizes on my Kindle and I'll send you an updated RST file when I have one. I downloaded the RST Zip file from PG and I'll be updating that rather than my original. You'll get it in a day or two, and I'll reply to your original email for the submission. Thanks for your help.

1. don't worry too much about the disk space. try to keep the images below 256K each. Images bigger than that will get shrunk when the ebook files are made. 2. 75% will look a lot better on html too. Remember, folks will be using phones to read html, it's not just Kindle. I'd go to 85%. Eric

Eric, Thanks for these suggestions. I tried 85% and except for one small illustration where I actually changed it to 25% it is a big improvement. I'm not going to worry about the disk space of the image files. Amazon actually recommends 300 DPI files for the Kindle, which is what I've got.
