Title: How to use the e-ink Kindle readers to display photos?
Question: The Kindle e-readers that lack full color displays also lack an app for displaying photos. Is there a way to get a series of photos to display? I realize they will be displayed in monochrome / greyscale, but it comes in handy for diagrams and illustrations.  Specifically, suppose I have a folder containing a bunch of JPEG images. How do I get them displayed in my Kindle?

sents: text: I done this with a Python program that resizes the photos on the fly to the screen resolution and then combine the photos as individual images in a simple EPUB, specifying no borders in the generated HTML and CSS.
text: The program was originally for combining scanned Manga images, but works for photos as well.

sents: text: Using LibreOffice Writer Create a new document and go to Format->Page.
text: Click the "Page" tab and change "Width" and "Height" to 3" and 4" respectively.
text: Note that the important factor here is the aspect ratio, not the particular dimensions.
text: You want to match the aspect ratio of your Kindle's screen as closely as possible.
text: Set the margins to a low number (⅛" is a good value).
text: Click "OK" to close the dialog and go to Insert->Picture->From File.
text: Select the picture you would like to insert into the document and click "Open".
text: You should end up with something like this: Go to File->Export As PDF.
text: Of particular importance here is the "Reduce image resolution" setting.
text: Using a value larger than 150dpi will just waste space in the PDF.
text: Make sure the option is checked and set to a low value (120 is probably a good choice).
text: Click "Export" and select a location for your PDF.
text: Transfer the file to your device.
text: Enjoy your pictures!
text: Note that you can pinch to zoom and pan on the Kindle Touch.

sents: text: I've got a 7th Generation kindle and found that I can upload PDF files directly via the USB cable, however I can't get images to upload no matter which of the options I tried that have been mentioned above.
text: However, Amazon provide you with a @kindle.com email address and you can email all supported document types, including images, to it (as attachments).
text: The files will then be stored on your device.
text: Just make sure that any images are included as proper attachments .. i.e. some email clients put images into the body of the email in a "Microsoft friendly format", so disable this option.
text: Please note you need to go into your kindle settings on Amazons website to configure which email addresses are allowed to send content to your Kindle.
