Hey Jimmy,
I am really sorry for the delay of this reply as it is a weekend for us here. Ah, we may have misunderstood your question earlier. You can resize the width and height of the category picture by adding the block of css codes below:
[gist]
body #eb .eb-mod-media-thumb {
width: 48px;
height: auto;
}
[/gist]
You can set the width to your own desired width.
