I want to Disable images resizing in k2, because if for example add an image with 510
pixels, it becomes 600, and the quality decreases, and
also a problem with rokstories module, how to disable image auto resizing?

Where can I find my answer, if there is no one answer me

put this code in template instead of original image code:

<img src="<?php echo JURI::root().'media/k2/items/src/'.md5("Image".$item->id).'.jpg'; ?>" alt="<?php echo $item->title; ?>"/>
