Can't find the loadSDLImage function

[WhatMeWorry via Digitalmars-d-learn]

I load the SDL3 library fine, but when i try and load 
SDL3_image.dll i get error:

libraries\load_sdl_libraries.d(170,22): Error: undefined 
identifier `loadSDLImage`

    LoadMsg imgRet = loadSDLImage();

I tried adding

import bindbc.sdl.image;

libraries\load_sdl_libraries.d(168,12): Error: unable to read 
module `image`
    import bindbc.sdl.image;
           ^
libraries\load_sdl_libraries.d(168,12):        Expected 
'bindbc\sdl\image.d' or 'bindbc\sdl\image\package.d' in one of 
the following import paths:
import path[0] = 
C:...\dub\packages\bindbc-sdl\2.3.4\bindbc-sdl\source
import path[1] = 
C:...\dub\packages\bindbc-common\1.0.5\bindbc-common\source
import path[2] = 
C:...\dub\packages\bindbc-loader\1.1.5\bindbc-loader\source


I've got the bindbc-sdl, -common, -loader which is all the 
dependencies required by SDL.
I've even tried searching through github trying to find 
loadSDLImage() function but with no success. where is this 
function?
