K2 Category module - Image bug

Hi,

I just installed the Publisher Quickpack Joomla 3.
I began to update/customize my website from this quickpack fresh installation.

In particular, I unpublished some of the k2 items.

I noticed a bug just after that : when I click on a category in the K2 Category module, the page listing all the K2 items relating to such category are not displayed properly, in particular, the image is not resized anymore to fit the page but is too large and goes beyond the module sidebar.

See in action here : http://jrey.o2switch.net/joomla3/
and click on one of the category.

Do you have any idea ? How can I solve such bug.
Kind regards,

After deeper investigation, it appears that when there is only one item published in a category, the image displayed at the top of the item, is not resized properly. When there is several items, the resizing is perfectly done.

Conlcusion, I have to draft several items !
