My big hobby is taking Photos (specially panora Photos … http://backblog.betriebswerk-landshut.de/tag/panorama/ )
Is there an Way to show my photos on OSM like panoramio does it for google maps…?
And Can I do that from my own Website … without uploading my Images to another Service …?
so there isnt an way to link them from my hompage or give them to OSM for example as an rdf??
For something on your own website, you could look at OpenLayers. http://wiki.openstreetmap.org/wiki/OpenLayers
This lets you show an OSM map with various layers on top of it. So it could be icons you click on to see a photo. Maybe with a KML overlay, something like this example: http://openlayers.org/dev/examples/sundials-spherical-mercator.html
