Adding new custom stickers to listing!

Hi:
I have read posts on stickers and found that stickers are picked from following file path
/so/framework/img/sprite_sticker.png
(The so is the theme name and name changes as per theme name)

The code is written in the file on following path which picks the sticker selected
/so/framework/class/class_admin.php

The sticker list is restricted to 10 names, I want to give dozens of names with different stickers and want to display on each product with different attractive stickers.

Now question is how to add more names with adding listing in ‘class_admin.php’ and adding more images in ‘sprite-sticker.png’ and then link together so that I can select from options and add to new listing?
