Inserting images - size changes

C

When my client inserts the images I've supplied (all with the same
pixel size) Powerpoint scales them automatically to 75%. How can I get
round this - without writing macros - simply and easily so I can
supply my client with a template and a library of images she can
insert herself? She is using a pc.

Images don't really have any specific size other than the number of pixels that
make them up. Some file formats allow you to include "suggested" sizes (TIFF,
for example). Most apps, including PPT/Win, will try to respect these sizes.

Other file formats don't allow for sizing information at all. In that case,
it's up to the program that uses the file to decide what size it should be. In
the case of PPT, the rules vary from version to version, but once you work out
how it treats a given image format, you can work out the numbers so it's
consistent.

Try this:

Create an image that's 1000 pixels wide. Save it as PNG and send it to the
client.

Have them Insert, Picture, From File to bring in the image, then right-click
and choose Properties. Have them tell you the width of the image from the Size
tab.

Now you know how many pixels (dots) there were in the image and how many inches
PPT made it. Divide dots by inches to get the magic dots per inch for that PPT
version.

Now if you need to make an image that appears at 10", you only have to make it
10 inches times XX dots per inch wide.

Thanks! That sounds more or less like the advice I got from someone
here, that we just make the images 125% and let ppt scale them to the
size we want. I've been assuming all the time that if I make an image
in 72 dpi it will show up 100% in powerpoint. But have been proved
wrong repeatedly!
