Can I scroll text atop an image that I chose?

[Guest]

does anyone know how to make texts scroll on top of a picture that you chose
and set as the background of the slide? the "credits" option only works if
the background was chosen from one of the "slide design" options.

Misha,
There should be no problem with your own picture.
See here for a thorough explanation of the credits effect and how to use it.
