I have a PDF that I've converted to PPT. I want to add a partner's logo to the footer of the document (image file, no text). However, when I add the logo to the master slide, it either doesn't appear at all or only appears on some slides.
I've tried resetting the layout, adding new sub-masters, but it seems really hit or miss. The document is 18 pages.
I've googled but can only find things that address text formatting in the master.
