Is there any way to make images in my gallery that look full and not square? If you check, the images of this link http://www.jouxbe.com/products.html appears complete and its not a square image. And on this http://centricalfit.com/rings doesn´t appear the sku text
It seems that you are using “Media grid” element of the Visual Composer. In this case you need to edit it in the admin panel and click “Modify selected” for Item Design
There you can change the height for your images to prevent them from cropping
