Displaying images in a table

Hi, I have a problem with displaying images in a table. In my computer (MAC) all look good (chrome, opera, safari, firefox, but in other compu´s, espcially PC's do not go all the images. Appreciate help on this one because I know nothing about programming tables. I have an old PC that displays well on "Explorer" but not in safari and Chrome.

Could you attach some screenshow with 'wrong' view ?

Thank you for your attention, the left is the failure, on the right the correct

Ok I can't see anything on this screenshots - could you give me direct URL's to this views ? I need to check the code so until I see the 'live' site I can't help you.
