This thread now covers all eink kindles, so it has a new less-restrictive thread title. As it turns out, I tested the instructions for the K4, and they work on the DX, DXG, and K3 as well. Cool!
Okay, I realize that this "images folder" business is old news for some, but "how to use it for comic books" was researched and documented by geekmaster and published in this thread where it can be discovered easily and used by many comic book fans. It also works for photo collections stored inside .zip files. Enjoy!
