Is there a size limit for presentations? (I am using ppt
2000.) My slide show is mostly jpeg photos and it is now
at 20 MB and I have more to add. Just wondering if I am
going to run into trouble.
 
Couple of thoughts:

1. Limited in size to your computer's ability to handle it (video, ram,
etc.)
2. How are you putting in your JPGs into your presentation? Might be able
to minimize file size!
3. Click "Tools", "Options", click the "Save" TAB and uncheck "Allow fast
saves". Resave and see if file size drops.
4. Click "File", "Properties", uncheck "Save preview picture" at the bottom
left. Resave and check it out again.

Holler back with your steps used in #2 above. Hopefully the others will
help your file size.
 
20 mb is not uncommon. I have seen files larger than 100mb (although rare). Large files take longer to load, but a reasonably fast machine with lots of RAM and good video card should handle it just fine.
 
It may also be that the image files are large because of the resolution they
have been saved at. You can resample the images to a 72 dpi resolution and
they will look as good and be a fraction of the size. You can read about

Mostly pretty good info, Dave. Thanks! But the whole 72dpi thing is a
fallacy. For example, if we both view the same 1000 pixel image on a web page,
one that's allowed to display at "natural" size (ie, not been given any
height/width parameters) how do you determine that it's 72dpi?

It's 1000 dots and on my scungy old laptop at 1024x768 it fills most of the
screen. On your hot new desktop rocket at 1024x768 it also fills most of the
screen. Only my screen is 8" across and yours is 18". That would make the
image 1000 dots per 8 inches or 1000/8 or 125 dpi. Or at your house, 1000/18 =
55dpi. Same image. Which is it?

I vote for "Neither". The image is 1000 pixels. Until you know how large it
will be displayed -- the "inches" part of the DPI ratio -- you've no idea what
dpi it is.

The best advice you can give people re PPT and images is to ensure that the
image size (in pixels) matches the video resolution (again in pixels) of the
system where the image will be displayed in PPT. The safest bet if you don't
know where the show will appear is to use 1024x768.
