talkimg It's been a problem for a while, I think this apps is doing development work. Very soon we will be able to upload images to this apps, just like we have uploaded images in the past, we will be able to upload them in this image. 
You don't have to worry because the developer is working hard for this, he is trying hard enough to solve it in a short time with all his efforts. So you wait patiently and calmly for a while.
