Even thought Facebook.com has released a lot of free Stickers, many people want to use their own stickers. There are two ways to do this. You can go to our custom Facebook Sticker page, and use the codes provided and put them in the chat box like you would a Facebook Emoticon.
Or you can insert your own custom sticker in a chat window. Below is a step-by-step guide on how to do the later.
First open a chat window and select the camera icon on the bottom right

This will open an explorer window to allow you to find an image. After you find an image, select it and hit the open button.

The sticker will now be seen in the chat window
