Problem with Portfolio

Hello.

Sorry in advance for my bad English. I am French and I use "google translate".

Yesterday I bought and install the template "GK_Photo".
My problem is that I can not install a Portfolio.
I'm creating a portfolio by creating a category and incorrect items related to search.

I create a menu link to reference portfolio (works without problem).
Once on the portfolio of the page I my images (test 2), but they are stretche.
Yet I have (I think) configured to have multiple columns.

Someone could he help me please.

I would like pictures in columns
