transparent png texture's bg looks black

[delizade]

Hi,
I have a transparent png. I want to mix this with a background by using layer_rgba node. I assign the bg to the layer 1. and assign transparent png to layer 2 but result has black background.
and Image node's details like below:
Resolution 768 x 1344 - RGBA8
Alpha Channels: 0
Layers: No

What should I do to use this correctly?

If I understand correctly, you want to mix the textures based on the alpha of your transparent image, right?

You can add the alpha output if you right click on the shader and select Add Outputs > Outputs > A.

If that's not what you're after, please give me some more details and perhaps images to show your expected output.
