Photo Tag game?

If you're using an imgur photo you need to get the BBCode image link or open the image in its own browser tab and pull that direct image hyperlink for input into the "insert image" on the forum reply.
The photo in your post is linking to the gallery, not the photo. The hyperlink should be https://i.imgur.com/duIlB8C.jpg or something similar.
I'm pretty sure you can't do this in the imgur app, it needs to be done through a browser outside of the app, which can still be done on android, it just takes a few more steps.
Also, you don't have to publish the photos after you upload them, that's only necessary if you want them available on the imgur public community website.
