On the first page choose "message board" from the size options.
Then click the "Choose images" box and select an image from your camera.
Your photo will appear with several selections below. Choose "Hotline for Website" copy the code and paste it right here on the message.
This works on all message boards. The good thing is, if your photo is sideways, you can turn it. You can't do that with TinyPic which a lot of message boards use for some reason.
