If you've ever used your own digital pictures in Power Point presentations, you may have noticed that your Power Point files tend to be quite large. If you've got a 6 or 8 megapixel camera, just a few photos can make your presentation eat up as much as 20 or 30 MB on your hard disk. (You don't want to e-mail that to any of your friends who still use dial-up.)
How would you like to trim that file by as much as 80 or 90%? You can! Here's how...
Open one of your "overweight" Power Point files.
Find a slide that has one of your pictures on it.
Double-click on the picture to bring up the "Format Picture" window.
For maximum file compression use the settings indicated in the figure above. You should not notice any significant loss of quality in your pictures, but when you save your presentation, you'll see that you've trimmed quite a bit off the file size.
