can't do mssngr at work - maybe later
open studio - click on one, then click edit or click create (new?). Starting a new one brings up the default one which has all the panels. It'll open a window with the logon on the left and an elements tree on the right. if you click in the logon you'll see the different areas highlight and the corresponding highlight in the elements tree. (and visa versa). The link I gave you has 3 screen shots in it. Look at the one in the middle. Center panel is the picture in the middle. It's a bitmap. Any panel using a bitmap would be an image you open in an editor. If you were to click on the pic in the middle, center panel would higlight and you would get properties listed. There's little buttons on the right of elements, click those and other options appear.
So if you click the girl, click on the bitmap button in properties and click edit, it'll open in an editor. That's where I did my clear all and paste new for mine.
I can't remember what's in 'Help' in the menu.
