Discuz code is not a language or anything that can achieve any function. It's the name of the forum, developed by a company, just a name. Just like bbsxp and Dynamic Web, it's just a name. Discuz code is developed in PHP language.

If supported, you can write a code in the personal signature file, such as [img] picture address [/img] Note: Generally speaking, the picture address of the forum only supports online pictures. How to get the address of a webpage picture: Find the picture you like online, and then right-click the property, and there will be an "address (url)" in it. Copy to [img] picture address [/img] instead of "picture address".

You can check the permissions of your own user group, and then look at the permissions of the next user group in your own user group to see what the difference is. Perhaps the highest user group (level influence) can use IMG.
