[Scribus] Assembling magazine pages

[D]

I currently would like to put together a magazine. However the problem that I am having
is that some of my images of quite large 1360px by 1280px and I would like for those
actually have a page to themselves, but I do know what custom sizes to make this and
other pages so that there no excessive paper showing behind the image.  How do I
customize the page for the image. Or rather convert pts to pixels?
