How to embed an image into Flash Builder 4.7

Hi guys!

I'm newbie when talkin about all these flash things.

I'll explain what I did:

- Project.as is the main project

- Assets.as is where I embed all images and resources

- Welcome.as is where I wanna show embed images and resources

Assets.as and Welcome.as are default , no edits, I mean:

package

{

          public class Assets.as

          {

                    public function Assets()

                    {

                    }

          }

}

And I wanna embed 1 image in Assets and then show it in Welcome.as

Can you give me entire code to put in Assets, so I can embed an image, and entire code to put in Welcome so I can show that image?

//english isn't my 1st.

thanks!:D
