Hello Bjørn, thank you very much for your work!
I see that when I visit my site with Safari desktop browser (5.1.7 version) the images are not shown.
This post is an example: http://en.amarseaunomismo.com/ley-del-dharma/
It is OK with Chrome, Firefox, Internet Explorer and Opera, but with Safari the images are not shown.
Thank you very much for any help,
PS: Safari 5.1.7 is the last version for Windows ( http://support.apple.com/kb/DL1531 )
