Thanks for looking into this problem.
You can find my page at the address: trommelaar.synology.me/peutroen/index.ph...nieuws/15-gpx-tracks
I'm running this site on my Synology NAS server.
You may find this site a bit strange, but that's because i'm using this site as my sandbox. When i'm satisfied here i'll promote the extention to the site i want to use it for. You can download de gpx from this page, but i'll attach it as well.
