New Post: Category tree symbol

Hi,
I like to set behind a category a warning symbol to warn customers that this category is only for certain purposes.
For example a flame to warn that the materials in this category are only for hot purposes.

For this I set behind the category name a link to the icon.
<p><img alt="" src="/portals/0/Images/Web/Emaille%20Hot.png" /> </p> However the amount of space to set this link is to less.
It cuts of the link.
Somebody has a solution for this?

With regards, Ton Hermes
