Full width template issue

I use twenty twelve theme.

My image size is 640x480px and everything is ok when I select random template, but when I choice full width page template, it shows jumbo size images, slideshow, etc.

I try to change my theme with other full width theme, but have same issue.

I use Ajax pagination with shuttle effect.

Any solution?
