WC has some members who are having technical difficulties with uploading in this Forum so the following work-around is presented:.
Do NOT use the blue New Thread icon per usual.
Instead go to Forum Tools which is in the blue bar to the right of the screen on the main page.
When you click on it a drop down menu will appear which includes "Post a new thread". . .
When you choose this option a new window will open allowing you to enter text and upload your image using the insert image icon per usual.
When you have completed your new post simply click submit and your new thread will appear.
