    PNGs over JPGs. I read about it in a iPhone development book. The iPhone OS optimizes PNGs and those are preferred, although JPGs would work just fine.

    Once loaded into memory any image becomes a simple bitmap. So in terms of the memory taken up its the same for most or all image formats. PNG may decode faster than JPEG.

    For what it's worth PNG is also a lossless format (theoretically no quality loss when compressed).
