Is it possible to use .png images for WiX bitmaps

Question

I am using 2 500K bitmaps in to display images on my WiX dialogs.

They dramatically increase the size of the installation package, and what is worse - it looks there

Answer 1

The WiX toolset isn't tethered to BMP and JPG. As you've found you could put any of those other image formats into your package. However, the MSI SDK only documents BMP and JPG support.
