There several posts on the Theme Designer. None seem to address the problem I encountered. I have tried to slightly modify background in Note Book theme. The theme designer does not allow for an alternative background. However, the background jpeg file can be located under the theme program Files\cyberlink\PowerDirector12\Style. When I substituted the background picture I desired (naming it the same as the original), the theme designer does not use the substituted images. Any suggestion on getting the desired background as part of a modified theme?
