Dear Flynax Family,

Some times user use a white background image and it look blended in with the main white background, not so clear like in screenshot below:

Is there any way I can add a background opacity 0.5 on top of that.
I tried :

section#listings div.picture > img:after {
position: absolute;
top:0;
left:0;
content: " ";
background: rgba(0, 0, 0, 0.5);
}
Any idea how to fix this?

Thanks
