Hey there,

I am really sorry for the delay of this reply as it is a weekend for us here.

Currently we do not have a setting to add new smiley from backend, but you have modify these following file to achieve this.

JoomlaFolder\administrator\components\com_easydiscuss\themes\default\structure\settings.js (Add new smiley icon)
JoomlaFolder\administrator\components\com_easydiscuss\includes\parser\parser.php (Add replace the smiley code to smiley image)
JoomlaFolder\media\com_easydiscuss\images\markitup\... (This file location is stored smiley image)

Sorry for interrupting into this thread but this is what I was looking for for a long time. Thank you Arlex. Is there a similar small tutorial for EasySocial smileys as well?

You can modify on this json file -> ..administrator\components\com_easysocial\includes\bbcode\adapters\decoda\library\config\emoticons.json

and put your emoji image in this folder location -> JoomlaFolder\media\com_easysocial\images\icons\emoji\..

For example :

// When I put this google emoji example

	"Google":	["(google)"]



// Your emoji image name and only png file format must same with this.

Google.png

Hope this help.
