Slide show is HUGE..

I've made a slide show of 106 pictures. All pictures
are in .PNG format and vary in size from 600K to 4 meg each.
The total of all pictures is almost 300 megabytes yet when I put
them in a slide show with "fade through black" transition I get a
file that is 1.5 Gigabyte in size. It grows from 300 megs to 1.5 gigs.
I can resample all the pictures but I lose some quality and really I
don't think I should have to since the pictures are only 300 megs anyway.
Any ideas of how to reduce the size of the slide show so I can put
it on one CD ROM?
Thanks,
Scott
 
You really do want to downsize those images, plus a number of other things.
Just because a CD will hold 300 MB doesn't mean that your end users will be able
to enjoy the presentation, or even view it.

Some reading to do:

Scott, there's no reason you want to use a single 4 MB image in a
presentation - even if it is fullscreen.

Sometimes, you get better compression with JPG than with PNG.

Also, if you are using a newer version of PowerPoint - do take a look at the
built in picture compression.

There's no reason I can think of for a screen show image to be 4meg unless
you're deliberately targeting very high resolution screens. An uncompressed
1024x768x24-bit color file will only be 2mb and change. A compressed file like
PNG should be smaller; possibly a good bit smaller.

How are you saving the file? Sounds like you might be saving to a previous PPT
version format. Don't do that. Unless you really need for people with PPT95
to view the file, it's not necessary but it's guaranteed to make your file
sizes explode.

The pictures are the sizes as they are on the CD
that came from Walmart when the film was developed.
They are incredible scenery of a mission trip a friends
daughter took into China. I'm trying to make the
slideshow where she can distribute it to people and I
burned it (the 1.5 gig show) to a DVD and it works
but is very slow starting. I've got it running on a laptop with
only 210megs of RAM but it's rough on the system; a lot
of virtual RAM manipulation going on I think. (grin)

Anyway, thanks for the information. I'll resample
the pictures and save them but I've already done a few
and there is a noticable change in clarity of the pictures
but I've got a very critical eye.

Thanks again...

That could be almost anything (or quite possibly there are several versions in
several different sizes)

Understood. Keep in mind that the pictures will get resampled no matter what.
Each computer has a particular video resolution it's set to run at and that's
what PPT has to work with. It has to resample your images to whatever size
that is. Handing it images that are a bit bigger than they need to be can help
it do a better job, but after a point, the tradeoff in file size makes the
presentation too large to be practical.

Let's back up a bit, though. How are you resampling the images? Maybe there's
a better way of doing that, one that'll give you results that suit you better.
