Where are the pictures filed on your computer? You'll need to hit the "browse" button to find them. When you hit that button, a box will pop up and list your computer's contents on the left. You'll need to first find the location where the pictures are on that side, then all the files that are in that location or file will show on the right. Double click the picture you want to upload to the board, and it will put the full "path" of the picture, which includes where on your computer the picture is and the name of the picture.
