How can I add a logo to a presentation?

I am trying to make a presentation with Mathematica and would like to know if there is a way to add a logo that will show in every slide.

I have not found any settings that would allow me to do that automatically and would like to know if there is a straightforward way of implementing this. I tried using a custom template with the logo but this also seemed impossible since custom templates are not possible, to my knowledge, with Mathematica presentations.

Any help is appreciated

Unfortunately your question does not appear in a form that would be well appreciated. What have you tried? Where have you got stuck? What are restrictions for appropriate answers? What does "ma" mean? –  Artes Apr 1 '14 at 11:10
I agree with Artes. Try DockedCells. –  Kuba Apr 1 '14 at 11:14
@Artes perhaps you appreciate more the edited version –  someuser_ Apr 1 '14 at 11:42
@Kuba thanks for the lead, even though i couldn't work out what i wanted –  someuser_ Apr 1 '14 at 11:43
@someuser_ Slightly better, but I'm still not quite satisfied. Other M.SE users appreciate when they can learn something from questions, even when they are not asked by leading experts. The better question you ask the more it will be appreciated, I hope this rule is still valid on mathematica.stackexchange. –  Artes Apr 1 '14 at 12:04
