Cannot change thumb image in specials block

[Kikert]

Hi, I have problem with specials block in PS 1.5.6.1. I wanted to change thumbs size to my custom one. So I created new size in backend and generated files (correctly, I checked the address).

 

Then I changed image src to 

{$link->getImageLink($special.link_rewrite, $special.id_image, 'main_discounts')|escape:'html'}

 

And I still have large_default image in this box. Smarty cache is disabled.

Can somebody suggest what's wrong?
