How composite png sequence onto zoompan?

I have the following command that successfully creates a 10 second video from a single image.

/usr/bin/ffmpeg -y -loop 1 -framerate 24 -i /var/www/html/data/photos/$image.jpg -vf "zoompan=z='min(zoom+0.0005,1.12)':x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)':d=240:s=hd1080:fps=24" -c:v libx264 -pix_fmt yuv420p -t 10 -s hd1080 -crf 20  /var/www/html/data/renders/$project_id/$scene.mp4

How would I go about compositing a PNG sequence on top of this clip. The PNG sequence would be named 0.png --> 239.png
