images not centered on mobile

Hi, how can I have the same padding on the left the on the right?
On the left is ok, but on the right it's too much white.

found a solution:
@media (max-width: 600px)
.ba-gallery select.ba-select-filter {
background-color: #fff;
border: 1px solid #f3f3f3;
color: #999;
display: block !important;
font-size: 16px;
height: 50px;
width: 80%;
}

Nice job!
