When you hit reply you should get a new screen with a box to type into. Above that box is a line of icons one of which is a camera (in about the middle) if you select that you should be able to inset your screenshot.
Thanks.
In case it helps here is the screenshot.

Your email address is visible in the screenshot, I suggest you edit the screenshot and repost before you get more spam than you can cope with.
Yes, select edit from the 3 dots in the right hand corner and delete the content of your post. You can't actually delete the post, just the content.
Thanks. I have replaced the image in the earlier post.

I now see that the image hasn't appeared, so here it is.
