wordpress layout

Hi,

I was fixing something in the resolution of the pictures, and suddenly the layout of my shop page has all moved to the left. How can I fix that please?

Also if you could help me with the resolution of the photos, they are 1200px x 1200px approx, I don´t know why are they blurry…

Thanks so much in advance!
