how to make resources exportable?

Shadowphile

I get this message but I don't know how exactly I am supposed to follow the warning:

W 0:00:02.373   load: Loaded resource as image file, this will not work on export: 'res://N0010_MainMenu/HM0010.png'. Instead, import the image file as an Image resource and load it normally as a resource.

Shadowphile Select the png file in the file system window, go to Import tab and select Image form Import As drop down.

Yes I did that on all of my images but I still get that warning.
I ignored it and exported the whole thing to a Windows desktop template but all I got was the first screen image then no reaction after that. Without the editor to debug I can't learn what is failing.
I just ran Godot again and captured the setup in this pic:

Shadowphile You did press Reimport button?

yup, every png being used (although the warning explicitly refers to the line of code shown above and THAT is certainly converted. I actually went back and made sure the files were updated.

Does this work?
HSmap = Image.load_from_file("res://N0010_MainMenu/HM0010.png")

In a Godot 3 project, I'm loading images this way:

const PLAYER_TEXTURE: StreamTexture = preload("res://assets/player_texture.png")
...
onready var player: Sprite = $Player
...
player.texture = PLAYER_TEXTURE

Some changes would be needed for Godot 4.

The first line didn't work.
Then I discovered that method doesn't exist in the 3.5 documentation.
I don't know why it doesn't flag an error for a method that doesn't exist. I even put in garbage letters and it STILL didn't give a warning.

The second method you describe explicitly loads the resources. That may work but I would have to import hundreds of images (perhaps in autoloaded global) Then I would have to remember every single variable name assigned to those preloaded resources throughout my code.
It's doable but definitely not preferable. Code is supposed to make our lives easier.

One other approach I have in mind is just to manually create every single scene with images already loaded into textrect or material.
Unfortunately, I still have images that are loaded dynamically although there would be far less of them to preload.
