How do I get rid of the white outline around the photos on the boxes in YafaRay?

I've been on various forums. Yes, Photoshop has this problem. There is a two-pixel-wide layer of translucent pixels along the border of the image on a transparent background. They give a white thin stripe in a high-quality engine like Yafaray. We need to remove these translucent pixels and that's it. Until I learned all the techniques. I did it very roughly, enlarged the original photo to a gigantic size of 10,000 pixels. And I cleaned the background with a hard eraser on such a small-pixel field. It works with a creak, but of course you need to learn simpler techniques.

Weird that Photoshop adds a two pixel border. It's probably meant as a transition border but it shouldn't be added without a setting to do so. Maybe try GIMP instead of Photoshop.
Most important: it would be great if you could remove that border and solve the white line problem.

It's not a problem in Photoshop, it's called antialiasing, it is required to get soft edges on transparent pictures. The problem could be that YafaRay doesn't handle half-transparent pixels correctly.
You could simply apply a threshold on the alpha layer to get rid of translucent pixels, see here:

PS. if you have the original picture, just turn off antialiasing when cutting the background.
