XF 2.0 How to add custom icons to each forum?

[Boils]

I wanna add my own custom icon to each forum, already tried Font Awesome mod that is available for free here but it doesn't have anything related to what my forums are for, so I prefer to upload my own images, anyone know how I can do that for each forum individually?

Try this in extra.less - replace X with your forum ID number

.node--forum.node--idX .node-icon i:before
{content: url('path_to_image.png');}
