Compress Picture

[Peter J. Hansen]

On my office computer I have PowerPoint 2002 (I think that's the correct
version) and I discovered what I thought would be a useful tool. On the
Picture toolbar is a button labelled something like "Compress Picture."
Clicking on the button opens a dialog box that gives one a number of
options including:

(1) Compress picture
(2) Delete cropped portion of picture
(3) 200 dpi or 90 dpi

Doing some experimenting with large tiff, bmp and jpg files, only (2)
above seems to reduce the size of the saved file.

Why don't (1) and (3) do anything?

Thanks.

If [Tools]-[Options]-[Save]-[Allow Fast Saves] is checked, you might not see
the difference in file size on save.

Allow Fast Saves is not checked.

If your pictures don't require compression, you won't see the file size reduced.
You would need to tell us more about the size of the inserted images and whether
you resized them in PowerPoint. Size measured in pixels that is. If you
cropped any of the pictures in the process of creating the presentation, then #2
will reduce the internal size of those particular images, as you've seen.

How do I determine "size measured in pixels" for photos in the various
formats?

You can open an image in a graphics editing program like Photo Editor,
Photoshop, Paint Shop Pro, or even Microsoft Picture Manager and find out what
the size is. The formats that are best are JPG and PNG. A properly sized JPG
would be about 100-150 KB max in terms of disk size. PNGs tend to be larger.
