Image to the back

Hi , i  have a custom login page with a image. But if i play with some heights and margins, the login container is not accessible, i think my image is my primary layer or something. I can not enter my password of click on the buttons any more if it is inside the image. How to fix this? Either to put my image to the back or put the container in front. It is not a default login page, but an alternative login page, not edited by css or sass, because of the password reset module. - Ricardo   Image:

Solution 1: Opacity settings for image and containers

Solution 2:  z-index and positioning at image properties (ex: z-index: -1;position: absolute;right: 0;top: 207px;opacity: 0.2;)
