Setting specific image file for background does not work

[Mis1eader-dev]

The following config:

[load]
#Specify whether or not to enable in the file dialog.
folderExt=false
#Specify whether or not to ignore errors (i.e. not show error popups when errors occur).
noerror=false

[image]
#Specifies whether the image is displayed randomly, you need to put at least 2 images
random=false
#Enable custom specified folder pictures
custom=true
#Image display position
posType=6
#Alpha 0-255 of image
imgAlpha=64
#Custom image folder absolute path (empty defaults to . /image)
folder=D:\Wallpapers

#Please put the picture in the Image folder first, and then img=specify the file name in the Image folder Is the file name, not the full path!
[D:\Wallpapers]
img="My Wallpaper.jpg"

However, this loads a random image in the directory.
