                return
        else
            ImgCache.cacheFile imgUrl, (cacheUrl) ->
                return cacheUrl

Enable debug logging in imgcache with :

ImgCache.options.debug = true;

then check your console.

Are you sure ImgCache.init has been called first? You could use the qimgcache.js promise version, it will automatically first call init if needed.
