Hoooraaah! It took a little time but it did work.
I used my iPhone for this.
1. In your imgur app, select the photo that you want to use.
2. Tap on the photo. Your “share” screen will come up.
3. Scroll down to “copy Link” and tap.
4. Return to your post. Select the “IMG” above the text box
5. in the pop-up, paste the link that you copied following the http// and press ‘next”
6 Add a title. I will try to do the above without the title to see if it works. It would save this step.
7. Finish your post and click Submit. Scroll up to the posts and you should see your photo in the submission.
Have fun.
