Optimizing the game package - > PNG into JPG+PNG

Blitz3D Forums/Blitz3D Programming/Optimizing the game package - > PNG into JPG+PNG

I'm trying to optimize all my 32 bits png images as they are pretty big in my (hopefully) finished game just to reduce packagesize.

The theory is instead of using 32-bits pngimages which is rather big sizedimages, I would like to use one JPG instead and apply a 8bit-alpha.png on that one instead.

Is it possible to do this on textured entities without having to rewrite all my code???
