How to use the e-ink Kindle readers to display photos?

                

        

        


    
    
                
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?

Older Kindles

On older generation Kindles (with keyboard) it is actually possible out of the box. You just have to store them in a very specific way.


Create a folder named pictures in your Kindle's root directory.
Create folders with arbitrary names for the collections you want to create.
Copy the images into those collections.
Press Alt+Z to start the image viewer.


You can then use the following shortcuts:

q = zoom in
w = zoom out
e = reset zoom
c = actual size
f = full-screen
r = rotate
nav controller = pan
page forward and back = cycle through images


I tested this some time ago on a Kindle3 keyboard and it worked.

Newer Kindles

I found a post on the Amazon forums. It claims that a similar approach still works on the Kindle Paperwhite.


Create a folder named images (not pictures!) in your Kindle's root directory.
Create folders with arbitrary names for the collections you want to create.
Copy the images into the collection folders. Make sure that the extension is JPG and not JPEG.
Select your collection.


I do not know how to select the collections, but I assume that they are listed along with normal ebooks. Feel free to add information on whether this works for the K4NT.

Kindle 4th/5th Gen


Zip your images. Name the zip what you want the title of this collection to be.
Copy the zip file to your documents folder.
Eject the Kindle and you'll find that name in your list of books. Turn pages to browse through the different pictures.

There is a hidden picture viewer in Kindle ( reverse engineered by Igor Skochinsky ):


Connect your Kindle to your computer.
Create a new pictures folder in the root of the Kindle ( next to documents, music, ... ).
Create subfolders e.g. book1, book2.
Copy image files onto the subfolders.
Disconnect your Kindle.
Press ALT-Z in the Home screen. New e-books will appear for each subfolder you created. Open the book and view the images.


I've tested it using my Kindle 3 Keyboard.

Using LibreOffice Writer


Create a new document and go to Format->Page.
Click the "Page" tab and change "Width" and "Height" to 3" and 4" respectively. Note that the important factor here is the aspect ratio, not the particular dimensions. You want to match the aspect ratio of your Kindle's screen as closely as possible.


Set the margins to a low number (⅛" is a good value).
Click "OK" to close the dialog and go to Insert->Picture->From File.
Select the picture you would like to insert into the document and click "Open".
You should end up with something like this:


Go to File->Export As PDF.
Of particular importance here is the "Reduce image resolution" setting. Using a value larger than 150dpi will just waste space in the PDF. Make sure the option is checked and set to a low value (120 is probably a good choice).


Click "Export" and select a location for your PDF.
Transfer the file to your device.


Enjoy your pictures! Note that you can pinch to zoom and pan on the Kindle Touch.

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.

The program was originally for combining scanned Manga images, but works for photos as well.

    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. 
However, Amazon provide you with a @kindle.com email address and you can email all supported document types, including images, to it (as attachments). The files will then be stored on your device.
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.
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.

On newer Kindles, use Kindle Comic Converter to convert a folder/ZIP/CBZ/etc of images to a Kindle format like MOBI/AZW3 for USB transfer to the documents folder or EPUB for Send to Kindle. It's the only way to get fullscreen images on Kindles.
It's intended for comics, but since comics are just images, this works too.
