I just want to also add that you should have given a detailed explanation on steps involved in uploading the image because when I clicked on the link and uploaded a random image just to know how it all works, I was afraid when I saw "uploaded" and didn't know the particular place the image was uploaded to. I guess you should have added that we need to copy the link and add it to our post and then preview it before posting it. But thanks for the information, it really helped.
There was a guide there:
The guide is the third link. But if desktop is used for it, it would have been better, and also if the images height and width have been adjusted. But with how it still is, you should be able to understand how to use talkimg from the guide.
