Flickr no image shown

[dennisklad]

Hi, the module works fine, but I find the bing photos a bit boring.

For some reason the flickr api does not work for me. It does not show anything.
This is my config.

{
        module: "MMM-Wallpaper",
        position: "fullscreen_below",
        config: { // See "Configuration options" for more information.
                source: "flickr-api:photos/154196032@N07;photos/146379395@N05",
                slideInterval: 5 * 60 * 1000, // Change slides 5 minutes
                fadeEdges: true,
                filter: "grayscale(0.5) brightness(0.6)",
                flickrApiKey: my_key,
        }
},

Is this a problem with the API? Maybe I have to wait until my app is approved?
