On the right side (nicely placed beside the ads of Victroia Secret stuff), under Upload Images and
Videos, you will see a Browse Button. Click on it and give it the location of your pics (whether you are getting them from your hard drive or a web site).
Click Upload, and the pictures will be saved in 'MY ALBUM'. Under those pictures, which you can view at the bottom of MY Album, you have various options (which I will not go into), but the URL address is important. Decide the picture you want to post, then click on the URL image, then press Control+C for copy.
Go to sailnet, and begin to type a new message or thread. In your thread (at the top) is a yellow button with the picture of a mountain. Press this and a pop-up will ask you for the URL location. Press Control+V to paste it.
