In unstable the image_transport plugins get their parameters through dynamic_reconfigure, so they're no longer hitting the parameter server all the time. It's also much easier to twiddle them.

Is your image_rotate node running on the robot or your desktop?

Have you tried setting compressed_image_transport_jpeg_quality

That should get rid of the error, but no idea if it will fix the lag problem.

This should probably be ticketed against image_pipeline.
