The admin will need to add them.
All he needs to do is find the images online somewhere and add them in the control panel and add shortcut keys
Control Panel » Images & Icons Graemlins
Select the tab at the bottom Add New Graemlin
and follow the upload directions.
Graemlins are the smiley images available for use in posts.
You may change the image for any of the Graemlins by using the browse box next to the graemlin.
The stock Graemlins may not be removed, nor may you change the UBBCode or trigger text.
Note: Deleting a Graemlin may result in broken images appearing in posts in your forums.
