Index page product resized images

Hello,
I entered to the admin section and changed the default values of the Small Image width/height from 100x80 to 130x100 pixels.
The thumbs shown in the sideboxes like New Product, Featured Product is increased.
But the images shown in the middle column of the main page is not getting resized to 130x100 pixels. I tried with other bigger values, still the same problem; sideboxes images change but the middle thumbs won't.
Is there some other way to make this work?

Thanks

Take another look in admin->configuration->images and scroll down the page.

There are separate settings for different pages/sections.

Try changing these:

image - product listing width
image - product listing height
