"Imagelist ignores the transparency of PNG and leaves with white background. It works on Berlin."

    Don't have the problem...but TSpeedButton do not draw the image properly, I have to use a TButton instead. (your project do have the problem but when I reload the PNG I have a transparent image)

    BTW you have to clear TSpeedButton.Glyph before changing the ImageList !

    Does the image have partial transparency?

    I think that TSpeedButton extract a Bitmap from the ImageList and draw it as a transparent bitmap (true or false) while TImageList can draw with alpha blending.
