I can understand the problem bro. But its a relatively new feature developed so give us time and we will try to improve it over time. Since we got the feature in 'working' condition i didn't wanted to delay the implementation so those who don't know can upload images.
Using this feature since it's implemented. No speed issues as Jio here is fast. Never used Imgur before so don't if its fast or slower compared to their app. Only issue is the image gets inserted multiple times. Perhaps I am pressing the Insert button too hard.
