Displaying PNG Logo in Tryton Login Dialog Using Sao.common.ICONFACTORY

Hello,

I am currently working on customizing the login dialog in Tryton, and I want to add a PNG logo above the login form. I’ve been using Sao.common.ICONFACTORY.get_icon_img() for adding icons, but I understand this method is mainly designed for vector-based icons like SVG.

Is it possible to display a PNG image in the login dialog using ICONFACTORY, or is there a more suitable way to achieve this?

The login dialog is not designed to be customized.
