CBZ files work on my K2i (CBR files don't).
CBZ = Comic Book Zip
CBR = Comic Book Rar


*** make copies of any folders/cbz/cbr files while doing this, just incase you muck it up

How to make a CBZ - select all the image files you want in the comic book (pages 1-9 need a leading zero, so 01,02,03 etc), and create a zip archive file of them (Windows... select all (CTRL A), RIGHT-click, "Add to archive" etc).

*** NOTE - use a picture manager program like Office Picture Manager or simply your OS to rotate any landscape (double) pages so that they are in a portrait (kindle position) with the picture sideways :-)

HOW TO TELL WHICH ones are portrait and landscape...

In an explorer window, make sure the "dimensions" column is up with the view on "details"... you should get something like this

01.jpg 800*1000
02.jpg 800*1000
03.jpg 800*1000
04-05.jpg 1600*1000
06.jpg 800*1000
then you can just RIGHT-click (usually) and select rotate C/CW


Once you have your zip file, double-click it to open it to check that they are all still in the order they should be.

If you're using windows (this whole reply assumes that your are), in an explorer window go to ORGANISE ---> Search and folder options (vista/7), or TOOLS ---> Folder Options (XP). In the VIEW tab of the folder options window, you'll find an option called "HIDE EXTENSIONS FOR KNOWN FILE TYPES"... uncheck (un-tick) this option, APPLY (and APPLY TO ALL FOLDERS), OK, and then get back to the folder with your zip file.

RIGHT-click the file and select RENAME, or just select the file and press F2.... the whole name of the file should now be selected and editable. Move the cursor so that you can (and do it)... delete and replace zip with cbz. Click ENTER and ignore the window telling you that the file may become unusable, by selecting CONTINUE or YES... whatever the option is that it gives you. You will now have a Comic Book Zip file :-)

HOW TO CONVERT CBR TO CBZ. Following the above method to UN-hide extensions for known file types (if you haven't already), rename the extension of the file from cbr to rar... again accepting the warning about changing the file extension. Your Comic Book Rar is now a normal RAR file. Extract all the images in the file to a folder, rotate any landscape double pages and create a CBZ as described above.

Hope that helps somewhat.

BTW... I haven't had a single problem with CBZ files on my K2i, except that when I sometimes open a comic, I have to hit MENU and BACK to do a quick refresh to eliminate any cross-over of a previous page.
