On your site it looks like you have solved problem by setting higher image sizes in css.

I have found the code line in style.css and for all who else may need its line 1778 that you have to edit.
It is possible to use a slider like categories slider or busness profile slider in the bottom , instead of block for premium ads? Is there any code?

Not quite sure what you mean, but if your problem has been resolved, create new thread.
