We remove the logo:
img#site-logo {
display: none;
}
Or maybe this:
.category-support img#site-logo {
display: none;
}
I added for clarity your photo:
.category-support .title a {
background-image: url(https://d3bpeqsaub0i6y.cloudfront.net/user_avatar/meta.discourse.org/ed_bobkov/45/177564_2.png);
width: 35px;
height: 35px;
display: block !important;
}
You may have to repeat this code 30 times.
I gave an example of how to do this without a component / plugin. You can implement it somehow differently. Although, css for 30 categories does not take up much space.
