right ok you need to upload your photos from your computer to an image storing site like photobucket.
So lets use photobucket as an example as I personally use it.
You make a free account and then go on your photobucket album page, there's a button to upload photos and you find your photo, say you saved it in my pictures, and then select it. It will be uploaded to the photobucket website were you can re-size it and edit it in various ways. To post it on a forum you click the URL button and it will give you the url of the image, then you can just copy and paste that into your post you don't need to press that little button with the mountain and the sun.
