Here's what I do to upload photos using Imgur. I have made some photos for this, if the board wants me to post them I can.
Also, if I'm not allowed to do this, mods can let me know. tks
Head over to Imgur.com
Click on new post
Click on choose photo/video
Navigate to where the photo you want to upload, click on it
The photo will appear on the Imgur screen, hover over the photo and find the “copy link”...
Click on the three dots, and select get share links
Select third from the top, BBcode (forums), select Copy Link
Go back to the form posts and right click, paste in your reply box, photo should appear.
