Hi There

I have a 44 slide presentation that I need to change the background on and really don’t fancy doing it slide by slide.

I have a background saved as a jpeg and also as a pp master slide and have also created a .potx template, but, no matter what I try I cannot insert this background onto the 44 slide ppt.

I am obviously doing something wrong because there must be a way, but if for example a click on the 1st thumbnail of the ppt I want to change, ctrl A, ctrl C then go to the ppt master I want to use and select paste using destination theme, slide 1 is a blank [but correct] master then the other 44 have a completely white background.

Please can someone point out where I am going idiotically wrong.

TIA
