Paint Shop Pro :: Alignment And Changing New Objects

All i want to do is create a new image... a black background to be exact which I can do easily enough, then I open a second image (a picture taken by hubble, im creating a new desktop background). I copy that picture, paste it onto the black background. All I want to do now is center the hubble picture on the black background. I can do it manually of course, but when I click on the hubble picture so that it is selected then go to the 'objects' drop down menu I see the 'align' option, it then opens another menu and it has it right there "center in canvas" but it is not selectable, actually the entire 'align' menu is grey meaning I cant select any of the align options.

Also, same project, the hubble picture... I want to but a border around it. Under the 'image' drop down menu is a add border option... but it adds a border around the black background/canvas and not the hubble image that I have selected!?! Why?

In both cases its like the program is not accepting that I have a new image (the hubble image) selected, its only allowing me to alter the initial black background.
