Can't load PNG file into ImageTexture

[sprite-1]

Godot version: 3.0.2

Issue description: The ImageTexture only accepts resource files instead of being able to take in regular images.

Steps to reproduce:

1. Create a WindowDialog node.
2. On the property inspector, try to add a Custom Icon for the close button.
3. Select "New ImageTexture"
4. Open the blank ImageTexture
5. Try to load a regular image file (you won't see it because only resources are accepted)

Step 3) can be done differently, which would actually solve your problem:
instead of "New ImageTexture", click "Load", and you will be able to use any PNG from your project.
It won't be an ImageTexture though, but a StreamTexture.

Even if it's not usual steps, ImageTexture should accept image formats though.

If I do that the close button icon doesn't change. So I looked at the default theme for Godot 3 and it used ImageTexture so I put two and two together and figured I need ImageTexture too.

That's even weirder... why would a StreamTexture make any difference? There are at least 3 issues here:

• Need to be able to import an image as an ImageTexture, or an Image, instead of a StreamTexture
• Ability to set a StreamTexture to change the icon
• Ability to load regular images inside an ImageTexture from the editor

Are you able to reproduce the issue of not being able to change the WindowDialog close button with an image?

I can't launch Godot right now but I can try to repro later

On a side note, keep in mind everytime you do "New TextureXXX" or "New Image" in the inspector, you have the risk that the data gets litterally saved into the scene, which means all pixels of the texture being written as numbers, which will make your scene go super fat.

Are there any updates on this?

I can confirm that "Load" on "custom_icons -> Close" has no effect and shows always the default icon.

This is now fixed via 317dee9 , although its kinda useless to do this anyway
