missing extension in files inside CBZ archives

[Andrea]

The files inside the generated CBZ archives have filenames like "000jpeg" (no extension) while the correct one should be "000.jpg" (this may prevent some comic book readers to correctly view them)

First of all thank you for your bug report. About the issue yes, the program acquires 4 chars for file extensions (usually .jpg, .png, .bmp, ecc...) but of course this method fails to get the dot when the file extension is 4-chars long, like "jpeg". I'll fix it in next version, thank you again.

v6.2 released, it should fix this issue ;)
