sidebox images are stretched in safari on my mac

Hi.

I can't find the culprit of the images in sideboxes getting stretched in safari on mac.
You can see example here:
www dot cadante dot com/index.php?main_page=index&cPath=66

Thank you

I checked your site on FF, IE and Safari and they all look the same.
index.php?main_page=index&cPath=66

Thank you.

On a couple macbooks that I have tried it displays like the attached images.

The safari versions are 6.0.1 (mac os 10.8.2), and 6.0.2 (mac os n/a)

And please do not post the link.

I still haven't found the problem here, any idea would be greatly appreciated.

Thank you
