I also decided to make things easier for fans of group banner images. Now you don't have to write long codes, everything is provided. 
You only need to make banner images and upload them to the forum. In the settings, specify the path to the folder.
The images themselves will adjust to the size of the user information block. It is enough to specify the original sizes of the uploaded images.
