If you are in Post Quick Reply mode then click on the third icon from the right. A window will open and it will have two choices: From Computer or From URL. If the picture is on your computer select From Computer.
Another window will pop up that says Choose File. Select Choose File and then a window listing your computer files will open. Find the picture file you want to post. Open the file. Click on the picture and the name of the picture will be put in the blank space. Select Open. Then click Upload File. All done.
Now my way: Right click on picture, select copy image, paste in post. This works 95% of the time for me, it depends on the app I use to open the picture.
