Okay i figured it out with a friend:
My code now looks like this:
Galleria.ready(function(options) {
// this = the gallery instance
// options = the gallery options
// will be called after the image is loaded
this.bind('image', function(e) {
imgHandle = e.imageTarget;
alert('Image loaded');
//will be called if on same server
$(imgHandle).exifLoad(function() {
alert('Exif loaded');
alert($(imgHandle).exifPretty());
//do something here....
});
});
});
});
And it works only with images on the server but not on remote servers.
