I was modifying something the other day and I think I inadvertently changed a setting that has now caused the product pictures to be in a single, vertical column on front page under "New Products for May", as opposed to the two or three across.

The front page now has 6 or 7 photos, one on top of the other.

I have looked and looked to try to work out what it is, comparing other web sites to mine but am stuck.

Could someone please tell me where I go to rectify this to what it was.

Thank you in advance.
