NSPGK5 cache how to avoid caching ?

Hi,
where can I set module NSPGK5 to disable cache ?
I set it to NO in the header module configuration and erased every jpg in modules/mod_news_pro_gk5/cache
but it keeps working

Hi

Select "Do not create thumbnails" instead. If this option will be enabled than module will use cache folder to store this resized images.
