Hi,
I have two singles (one is image placeholder, another one is actual image). I want to merge them, get onNext only once if the actual image is returned first, else get placeholder first, then image.

I can use concat, but it always returns placeholder first them image. After the image is loaded, image is get from cache. so there is no point in showing placeholder if image is got already.

Thanks.
