First off, you'll need to be logged in and submit your photo into the gallery.
Then right click on the photo you want, and select "copy image address".
Then click into the thread on the message board you want, and click the "post reply" button. You'll see it at the top and bottom of the page.
This is where you can write a reply. To add your image, look for the little image square button and click on that.
A little box will pop up, and then you will paste your image link there. Either right click and select "paste", or use control + v (or command + v) on your keyboard. Click the ok button.
And there you go! Add any text you need, and click submit on the bottom and it will be posted to that thread.
If you are on a phone or tablet - the directions are mostly the same. In order to get that image link though, you'll need to tap the image first, then tap & hold to get your options. There should be a copy option. Then you'll paste in the message board using the same image box.
Hope this helps! If you have any questions please ask!
