On the new post at the bottom of the Contest Thread, select the upload a file option 3. Find the screenshot in your hard drive and select it. 4. Click on either Thumbnail or Full Image to display your screenshot in your post. 5. Click on Create a Thread 6. Have a cup of tea to celebrate! Don't despair if it doesn't work first time, as a new Forum Mod in 2017 I struggled no end with this!!
