Hello everyone! I'll show you guys how to add Interface Icons to an item name!
First put your desired icon in the first slot of your bag like this: http://prntscr.com/2wsnhb
Next type this macro in to discover what icon it is: /run local x =GetContainerItemInfo(0, 1)print(x)
Now copy that down, so you should have: Interface\Icons\Mail_GMIcon
It's important that you edit it so it looks like this or it won't show up correctly: |TInterface\Icons\Mail_GMIcon.blp:15|t
(the .blp:15 part controls how LARGE it is. So .blp:15 is TEXT size, if you want it to be bigger simply increase the number, or smaller decrease the number.)
Alright now that we've got that all done open up Heidisql and go into your item template and edit or create an item and simply put |TInterface\Icons\Mail_GMIcon.blp:15|t in front or in behind of the text you want and it'll come up in-game!
