I recently managed how to get rid of white background, but the other concern is that I want to put white frame around each image. Like it's here https://goo.gl/hqqlvw. I want white frames to appear on all images, including: catalog where all products thumbnails are shown, product page main image and product page small thumbnail image below main image.
All images which I upload are not the same size. So system should know the size of each image I upload and put white frame around it.
Where can I find this option to put white frame? Or I would need to use module for this? What are your suggestions guys?
At the moment I have this look: https://goo.gl/ttQ9kU
Thanks for letting me know.
