Specs for creating a background image

[Joann Schmidt]

My creative dept. is getting tasked to create background images for corp.
ppt's. I've told them to start by creating the background 10"x7.5" at 300
dpi. Once they have the image designed and approved they then reduce the
physical image so the size of the file is between 3-5mgs. I tell them to
leave the resolution at 300 because PowerPoint will drop it down to 72. Is
this ok? Is there a better way?

Joann,

Starting off at 10"x7.5" @ 300dpi is a good idea

Then if you down sample something it will keep the quality.

I tell them to leave the resolution at 300 because PowerPoint will drop it
down to 72

That's kind of not correct. When the image is shown during a slideshow,
powerpoint will have to look at that massive file and chuck away the bits
that will not fit at whatever resolution you currently run your screen at.
It's best to do that yourself and give powerpoint less to do.
