I have a theme which I installed which I really like.

I have a theme which I installed which I really like. I have it mostly configured to do what I want however there is a small thing I would like to change. When creating a new blog post there is an option at the bottom (link here: https://i.imgur.com/WzTzLfw.png) called 'type icon' which lets me select one of a limited number of lame icons that fits in the box which is created next to each new post. (see here for example: https://imgur.com/xY3fuer)

I would like to upload my own image instead of selecting these 'type icons' Is there any way I can code that in to the theme?

I have enabled remote access to the site and am willing to work with anyone who can help! Sorry if this is a large request :slight_frown:
