The problem of gray images and control_panel_default.png

After installing the module in Drupal 5.9, all images displayed as - control_panel_default.png. I have reviewed the source code module and understand his work. Part of the work is to transform the URL and displaying the appropriate images. Ie http://mysite.ru/node/add/story corresponds to the image node_add_story.png. For the normal display of images, I had to rename the original images (controlpanel\images\48x48 - I use size: 48x48).

Ie admin_settings_controlpanel.png renamed control_panel.png.
