Downscaling/transcoding images to 1080p prior to sending to Kodi for faster slides

As Kodi (at least on Raspberry) is limited to 1080p anyways it would be awesome to limit the amount of data that has to be transmitted by reducing picture-size.
This should improve performance vastly and “diashow” should even work with large files.

It may be sufficient if it’s possible to send only the android-previews (which are in a totally different folder)?
