Master slide background - jpeg or 'build from scratch?

I have had a branded background design professionally created. Should I use a
jpeg of the design as the template background or re- build within Powerpoint?
Which of these options is more file size friendly? If jpeg - to what size
should I have the file saved and how many dpi? Are other file formats better
than jpeg? Any advice would be appreciated.

Thank you

I'm not sure I see much of an advantage to rebuilding the whole thing. You
should be fine with a picture format (either JPEG or PNG). Don't worry
about dpi. Instead, worry about total pixels. The total pixels depend on
the size of the screen that you want to display this on. A typical screen
is 1024x768, so you could probably just size your picture for that. You
could go larger (keeping the same proportions), but that would cause the
file size to be bigger, so it is a bit of a tradeoff. Note that large
wouldn't make it look better on a 1024x768 screen, but it might make it
better on a larger screen.

Thanks David. The presentation is a training program and will be projected -
what in that case is best practice for pixels ?

I'm stuck between a graphic designer with high technical expereince and low
ppt expereince and a trainer with alot of ppt presentation experience but low
ppt technical experience!

Do you know how the file sizes compare from build it yourself to jgeg?

This still depends on the resolution of the projector (don't think
physical size; think pixels). Just because a projector projects onto a
giant screen that is 8 feet by 6 feet, does not mean that it's resolution
is any higher than 1024 x 768. If it is 1024 x 768, you will get no
benefit from making the picture any bigger.

The one advantage with build-it-yourself over JPEG is if your background
contains a lot of text AND you are using a known machine to present it.
Sometimes text loses some of its clarity when it is in a picture format.
However, if you are using this on several machines, font differences from
machine to machine could cause you more problems, making a picture format
your best bet.

Also, note that this isn't "rocket science." If you have a picture
already designed (I think your original question said you did), try it
out. It should be easy enough for your designer (or you) to make several
different versions at various pixel levels and in various formats (such
as JPG vs. PNG). You can compare the file sizes yourself and take it to a
few different machines with a few different projectors to see which
formats you try have acceptable quality.
