Is it possible to show a category logo on all topics within this category? I speak about “logo small”.
In my case it’s more appropriate to show a logo connected with this topic than a general site logo.
Thanks!
Do you want the logo to be displayed on a topic itself or also in the topics list?
I guess you can do that using some CSS.
Or editing templates… 
How many categories do you have?
If there are a reasonable number of categories, then this can be done through css. Just redefine the logo at the top. Using:
<body class = "category - ***
category-support, for example, in the topic in which we are now.
I’ll have a fix number of categories - 30.
Not sure what code to add to css. Can you give me more obvious hint? 
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.
Thanks! That’s working with some changes.
Hint: category name I should take from “Category Slug” in category settings.
Logo sizes may be different:
width: 65px;
height: 50px;
display: block !important;
background-size: cover;
