PPT Pictures - determining resolutions

[JohnNearSyracuse]

I have over 200 pictures in my PPT 2004 for Mac presentation,along with
many animations. I believe I need to decrease the resolution on some of
the pictures to decrease the overall file sizes, since the file sizes
seem to be too large. Each of four segments of my presentation are
12-16 mb, connected by hyperlinks. My questions are: 1. Is there a way
to determine what the resolutions are for these 200 pictures I have in
the PPT presentation WITHLIN PPT, or must I export each of these photos
into an external photo processing appllication to determine the
resolution of each? (I only have IPhoto on my Mac Powerbook G4)
2. I have read about external applications that one can purchase to
decrease the sizes of PPT presentations. Are any of these "safe and
effective? And if so,please refer me to a website.

I don't know of any way to check the resolution w/in PPT.
If you have the original images, I'd check those.

I'm not near the Mac so can't check this right now; if iPhoto won't let you
resample oversized images down, you could use Grab (from your Utilities folder)
to snag screenshots of the images as displayed in slide show view then insert
those into PPT in place of the originals.

2. I have read about external applications that one can purchase to
decrease the sizes of PPT presentations. Are any of these "safe and
effective? And if so,please refer me to a website.

Most of them seem to be Windows applications or PowerPoint/Windows add-ins.
I don't know of any that run on Mac.

Hi John,

You can save individual pictures into smaller file sizes by
control-clicking them and choose Save As Picture. You can control the
file size somewhat by going to PowerPoint's preferences and click on the
Save tab. The picture formats don't all adhere strictly to the settings
there (known bug). These are the largest sizes that the pictures will
save in regardless of the setting you choose:
TIFF 72dpi
JPEG 72dpi
PICT 1200dpi
PNG 300dpi
BMP 72dpi
GIF 72dpi

Once you save the picture, delete the one in the presentation then drag
the one you just saved back into the presentation.

There are some products that can trim file sizes of presentations.
Impatica offers a good balance between screen quality and file size.
