Should I change photo background from white to grey (#efefef) in bulk for all the goods before uploading the images?
You can navigate to the Colors section under the Customizer window to choose a color, view color suggestions, refine with the color picker, & apply background color changes.
I see. But the background of the image must be transparent. http://10000top.ru/product/kofe-v-zernah-egoiste-noir-250-g/. Could you advise me the colors for FMCG site?!
