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 ...

Part of the program I wrote for scanning and EPUB-ing scanned images can be reused for this purpose. I tried to make a minimal version, the output was tested with calibre book reader and a BookEen reading device and passed EpubCheck version 3.0.1 without errors. The program requires you to provide a Title (--title) and one or more JPEG files, which are ...

You can't float to top or bottom. But you can use the CSS break-before property to ensure a page-break before your pictures. Obviously, this will put pictures at the top of the page.

Calibre has had an option to insert a cover long before it offered editing some ebook formats. That option comes with additional utilities of finding a fitting cover using some internet services. If such a cover is not selected, calibre generates its own and inserts that in the epub file. With the relatively new editing possibilities in Calibre, the cover ...

This depends on where you are publishing your e-book, and is subject to change. With Kindle Direct Publishing, they require a minimum of 625 pixels on the shortest side and a minimum of 1000 pixels on the longest side, but they recommend 2500 pixels on the longest side. With Nook, they require that the height and width be at least 1400 pixels, and the file ...

The short answer is no, and I don't expect there to be anything like that with a single recommendation. The reason is that different input material is better rendered in different image file formats. All material handles well in non-lossy formats (among others most of the TIFF formats, PNG), however such format produce large files. When you look at space ...

I think that for a collection of images maybe the EPUB format is not the most suitable. If you just need the pictures without any text, and if your reader support it (as far as I know, most of them do it), I would suggest using a comic book file format like CBZ or CBR. These are standard ZIP or RAR files (the only difference is that their extension has been ...

Note: I intended to leave this as a comment for @mosh but didn't have the necessary rep. This is my own personal solution based on the solution he outlined. This will recursively scan a specified directory and compress files larger than 49MB, overwriting the original files. [I chose that size due to the fact that Google Play Books uploads are limited to 50MB ...

This is possible. However, you must jailbreak your Kindle first. Basically you: Jailbreak the Kindle. Load the screensaver hack to your Kindle. Copy the images to your Kindle. This site has a list of places to get these.

It depends from the type of images you need, but I'd suggest to have a look at openclipart. Its great advantage, besides containing images with an open license, is that they are stored in vectorial format (SVG), so they may be scaled at will.

unfortunately you can't make width:100%; in mobi files. Amazon just strip that away. You can try to set min-width:100%; instead but this is little different in behave so test are needed. More about which CSS kindle respect you can read in this documentation. 2017/06/27 Changes in KF8 format allow now using width css property

calibre already has a tool for this, but it isn't a plugin. It's part of the ebook editor that installs with calibre. The editor will only edit files in the epub or azw3 format though. You can convert the mobi file to azw3 and then edit it. Converting it from mobi to azw3 may automatically downsize the file, but I'm not sure. Once you have the file opened in ...

I had a similar situation: a 134 MB .mobi that I wanted to shrink. Here's how I reduced the file size to 26 MB. The key to this approach is that an .epub is actually just a zipped web page with image files in it. Converted the .mobi to .epub with Calibre. Renamed the .epub to .zip. Extracted the .zip. Note the images subfolder. Mine had more than 1000 ...

bash script to for bulk compressing images in big.epub to small.epub on Windows7 or Linux.

The fastest and simplest way is to use a comic book archive format. If you already have the image files, make sure that they are named with the correct alphabetical and numerical order (I.E. cover.jpg, page001.jpg, page002.jpg and so on); the program that you will use to read the comic will display your images in alphabetical order. Then you can simply ...

The short answer is that with few exceptions you should NEVER need to scale down .mobi files because Amazon.com will do it for you. I think 5.5 MB is a reasonable file size for an epub file. I don't know if it is a typo, but 60MB is a bit high for mobi files. However, when you buy a .mobi file directly from the publisher, the preferred way to get it to ...

So, I am not a lawyer, etc. The basics of copyright law, though, are fairly straightforward: If you don't own the image/text/song/whatever, you can't use it, unless there's an explicit license in place that lets you do what you want to do. There are some specific exceptions in place, like parody (which is about creating transformative work from pre-existing ...

This answer does not present any legal advice. In fact your post contains two questions. Speaking of the youtube license part you should definetly add information about the country you want to publish the eBook. CC licenses come with different characteristics, regulating the rights and responsibilities. The use of CC licensed images may be limited in terms ...

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 ...

Here is a Python script I use to automate reducing the size of epub books: https://github.com/murrple-1/epub-shrink Example usage: $ python epub-shrink/app.py input_file.epub output_file.epub --jpeg-quality=25

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.

Testing this it seems that this is simply a quirk of Calibre's ebook viewer. It adds the absolute calculated size of the image dynamically into the source. This size changes when you resize the window (with the inspector window open it shows continuously). Whether max-width and max-height styles are set by the viewer depends on the viewing mode. In page mode ...

Wikipedia has many image that are in the public domain or with acceptable free licenses. I would assume that—with proper attribution—you can use images in the public domain, and part of the free license, in your own work. On this site you can see the stock-photo-licensing agreements of various suppliers. I have a—now unused—...

Is there a way to force KF8 output, or to float images in MOBI7? Unfortunately, you can't generate KF8 dictionaries and it's unlikely that this situation will change anytime soon, because Amazon inherited the code from Mobipocket and has only implemented cosmetic changes so far: Note the following KindleGen message: Info(parser8):I12001: Enhanced mobi ...

You could try with standard CSS rules and see if the results work for you. Example for the background: body { background-image: url(../Images/image.jpg); } You can also try other background rules (reference). Same thing for borders, you can try standard CSS rules: body { border: 1px solid black; } (Reference for borders, margins, padding). ...

Ultimately, it depends on which ereader devices you want to support. Unless you are making a fixed layout book, the only method that will work 100% of the time is to make the caption a part of the image. Since epub and mobi are reflowable document formats, there is always a possibility that the device being used to view the document will push a text caption ...

Here is the css I use for my kindle images: div.image-container { width: 95%; margin-left: auto; margin-right: auto; } div.image-container img { width: 100%; display: inline; } The goal I wanted here was to have an image cover 95% of the screen, with the image in the center. You could change the 95% to 25% if that is what you want. I do not ...

The easiest solution what I found is Kindle Comic Converter, which also cuts the edges. I used it several times, and worked fine (didn't cut into the text, etc.)
