Category images incorrect size / blurry

WHen hovering the categories with image list the images are incorrect size. Their origin is 50 x 38px but blown up on the page.  Possibly the error is using the "_50" image while the "_300" seems correct.

<div class=">
   <a href="/samsung-watches" title="Show products in category Samsung Watches">
      <img class="lazy" alt="Picture for category Samsung Watches" src="http://tvrwebshop-staging.azurewebsites.net/images/thumbs/0000456_samsung-ur_50.jpeg" data-original="http://tvrwebshop-staging.azurewebsites.net/images/thumbs/0000456_samsung-ur_50.jpeg">
   </a>
</div>

Hello,

the category image dimensions are determined by the corresponding setting on the "media settings" page in your administration. When a setting is changed there it is also necessary to clear the cache from the admin panel otherwise the new setting will not be applied on the website (as the images are all cached).

If you have a persisting problem with image dimensions please open a support ticket at nop-templates.com
