It wil be converted when export to PDF and choose "printer" as destination.

It's not the import/export process, it's the file formats themselves. PNG can 
only consist of 256 colours, so it's of few to no use for photographs. It is 
only useful for screenshots or other graphics with only a limited colour 
range. The advantages of PNG: lossless compression and transparency.

HTH,
