add image link as tab

Hi,

I would like to add a link "add image" as a tab, when viewing the own album (album per user) as logged in user. This should be the same function that is provided by the "quick links" block ("Add an Image").
I tried to add the Tab by inserting the following code into acidfree_menu() function:

               $items[] = Array('path' => "node/add/image/{$path[1]}",                        
                        'title' => t('Add image'),                    
                        'callback' => 'acidfree_page',
                        'type' => MENU_LOCAL_TASK,
                        'access' => user_access('edit own acidfree albums')); 

Right after the code, that includes the "Album contents" tab (line 419). But it is not working this way. Can you support me in adding the Tab to my Acidfree albums?

Thanks in advance and kind regards,
Hauke
