RS Collage node not displaying any images on ComfyUI v0.22.0

[aastle]

I connected two Load Image nodes to the RS Collage node but didn't see any images in the node. The overlay image is a png with a transparent background. I tried connecting the mask output to the mask input of the RS Collage mask. I am using the latest version of ComfyUI portable for Windows 11 Pro. My browser is Google CHrome, latest version.

There are two formats for PNG images with transparent backgrounds: RGB+Alpha and RGBA. The node accepts the RGBA format. The readme file states that the node accepts the RGBA format.

ComfyUI treats regular PNG with transparency as an image on a black background, so to work with transparency, it needs to be converted to RGBA format.
To do this, you need to either connect the RS rgb2rgba node (located in this node), which automatically converts your image to the correct format, or take the image from the image output of any node that crops the background (RMBG - Remove Background (RMBG), BiRefNet Remove Background (RMBG), Florence2 (RMBG) etc.)

For the background you can use any image loader.
