I don't know where to post my question, so I just put it here.
I'm using com_k2-v2.0.0_j15-build20090701.
When I browsed throught the demo pages of K2, I found that the layout are very impressive and nicely.
However, I could not reproduce that on my testing server. I want the Item image and the Item description to be displayed side by side in the Item listing. What I see on my production server is the item description goes under the item image, no matter I change the K2 template from "default" to "Blog", or to change the number of "leading", "primary" or "secondary" in the category item layout.

Did I miss anything, or I need to edit my own K2 template?

Any advices?

Many thanks.
