Convert JPEG to CBR

You can create your own CBR comic book archives manually, if you simply rename your all the JPEG (.jpg, .jpeg) files you want to put in to a 001, 002, 003 etc. sequence and  compress it using a RAR program. After that, just rename rar to cbr and that's it. You can even find programs that can automate and speedup the creation of these comicbooks.
