Wrong visualization in Kindle 3 (Keyboard)

[ciromattia]

Using KCC for use in Kindle 3 correctly generates the .mobi, but the Panel View is kind of messed up:

Zooming, though, displays page bounds correctly, so I assume it's some issue with OPF options or resolution (converted image for the screenshot is 492x800, attached)

It seems an issue on automatic generation of the original-resolution meta parameter on the OPF, if the first image is sized differently of the others:

<meta name="original-resolution" content="600x615"/>

Changing it to

<meta name="original-resolution" content="600x800"/>

solves the issue (though the pages that do not match entire width are all left-aligned)
