If you have a picture 'on line' storage places like PHOTOBUCKET, I have been using the 'Direct Code' for the picture and I place that copied code in the space provided when I'm posting. Click on that yellow icon thing above every post. It has that has a black mountain and a black sun in the upper right hand side, on a yellow background. Rest the curser on it and it will tell you, "Insert Image".
To post a picture from PhotoBucket, Left Click on IMG Code under the picture,
then right click on the blue highlited part and it should copy,
then just post it in the thread.
