You'll have to add the icons either by overriding the appropriate views or by making use of events. The category icons can be output using the CategoryPhoto() function located in the category helper functions. Here's the basic code you'll be needing:

// Include category helper functions
include_once $this->FetchViewLocation('helper_functions', 'categories', 'vanilla');

// Write out the category photo
echo CategoryPhoto($Category);

i wanted to show the logo of the level3 forum categorys at picture 3 .

after i copyed the views/discussions/index.php to my theme file and added

echo CategoryPhoto($Category);

to after line

include $this->FetchViewLocation('Subtree', 'Categories', 'Vanilla'); 

it showed a logo ...... but it's a logo of level2 forum , not a logo of level3 forum.

Here is what you need to get started with outputting the sub-category photo in Vanilla 2.1+.

1. Create a file called class.THEMENAMEthemehooks.php. Replace THEMENAME with your theme's name in lowercase.

2. In the file, you would need this and replace the word "THEMENAMEThemeHooks" with your theme's name in camel case:

<?php if (!defined('APPLICATION')) exit();

class THEMENAMEThemeHooks extends Gdn_Plugin {
   public function CategoriesController_AfterCategoryTitle_Handler($Sender) {
      echo CategoryPhoto($Sender->EventArguments['Category']);
   }
}

This will output the category photo in the subtree view that is displayed when viewing the first level category. You can then add some custom CSS rules in your theme to style the sub-category icons.

Also, you would need to check if you are viewing a category and not the categories index since the AfterCategoryTitle event is also fired on the categories index.

For example:

<?php if (!defined('APPLICATION')) exit();

class THEMENAMEThemeHooks extends Gdn_Plugin {
   public function CategoriesController_AfterCategoryTitle_Handler($Sender) {
      if($Sender->RequestArgs[0] != '')
         echo CategoryPhoto($Sender->EventArguments['Category']);
   }
}
