Some of our Generation 3 templates allow you to choose 2, 3, or 4 images per row.
For that feature to work properly, you must have "Use Variable Size Thumbnails" set to Yes in your "Edit the works display" section. Normally, when you choose a template that needs the setting in place, we automatically set it. But, if you are experiencing this issue, please make sure that the setting hasn't been changed.
