I suggest using Google Image Search.
Type in something like "pirate humor" or some other key words.
When you see a picture you like, click on it and you will have a split screen. At the top will be a thumbnail of the picture, along with a link to see the picture full size. The bottom part of the screen will be the page that the picture appears on.
If you click on the link to see the picture full size, you will have the address of the picture in your address bar. Copy that address.
When you post, click "Img" then paste the address, then click "Img" again.
If you want to make sure you did it right, click "Preview"
