Show Sub Category Image above Category Navigation

I want to show the sub-category image on the left navigation pane of the current selected sub-category  together with the Category Navigation.

I have created a the following setup:

Main Category > Sub Category 1 (show sub-cat image if active)
                      > Sub Category 2 (show sub-cat image if active)
                      > Sub Category 3 (show sub-cat image if active)

Do you guys have idea on how  to do it?


Thanks,

if (currentCategory != null && currentCategory.CategoryId == category.CategoryId)
  { link.CssClass = "active"
    //you should create an image control here
};
