GPX File with links to images don't word

I tried to load a GPX file into the plugin, which refers to image-files on the server, but this does not word.
Only a world map is displayed.
Isn’t it possible to link to an image file or is there an error in my code?

`<wpt lat=”40.5830555555556″ lon=”-74.1566666666667″><link>http://192.168.0.100/wp-content/uploads/path/to/directory/2015-10-14_12-03-59.jpg</link></wpt&gt;
