all my image sizes are 330 x 330 px (width x height). How do I resize image on product detail page (above url) so image is not blown up like it is showing now please. Thank you in advance.
Since you're using Smartwave Porto theme, you should be able to do resize here:
System > Configuration > Porto > Porto - Settings Panel -> Product View.
Here you have options:
- Keep Image Aspect Ratio
- Image Width (when Keep Image Aspect Ratio is no)
- Image Height (when Keep Image Aspect Ratio is no)
Try to change those values & clear the cache. Let me know if you succeeded.
