[info] a shader that displays a png image.

[0wwafa]

I wish to have a shader that instead of the "source" displays a PNG image.

I have no idea how to do so.

I need it so I can test some shaders with a known source.

You can just load the image directly in RetroArch via 'load content'. Many of the shader authors do this for testing specific scenes/images.

yep I know that but I am not using retroarch but DENISE emulator.

in that case, you can use the imgborder shader. Just don't have an alpha cutout and it'll cover the whole image.

It does not work for me. I need a simple shader that takes a PNG and use it as SOURCE instead of the emulator (Denise Emulator) so that I can use it to fine tune shaders.

works fine here.

imgborder looks for a texture named 'pvm.png' in the borders/textures directory. You can either edit imgborder.slangp to point to some other image or you can rename your image to 'pvm.png' and overwrite the existing one.
