Wordpress comments emojis plugin

Some methods have been modified. The emoticon can be directly read from the directory. Now you can easily add or remove emoticon images. You only need to put the images in the face Directory. However, Chinese image names are not supported yet.

<? Php Tutorial
/*

1. You can add or remove emoticon images in the face Directory (Chinese characters are not supported currently)
2. jpg, jpeg, png, and gif emojis are supported by default.
