Image resampling in PPT?

[Guest]

Greetings all,

Please bear with me as I'm a PPT newbie, trying to help the even more
novices in our Marketing Dept. get their presentations ready for
distribution via our intranet.

The PPTs I'm working with are huge, 20-25mb each. There are a lot of photos
in each file, and it appears that when you insert a large photo and then
reduce the size it within PPT, it does NOT resample the image.

Is this correct? I had a look but I can't find any options or commands to
resample the photos down to a reasonable size.

Am I missing something, or must each photo be resized and optimized
externally, and then inserted?

Thanks, and Happy Birthday America!

That depends.....powerpoint 2002/XP/2003 have an option to "compress pictures". It's on the picture toolbar

Powerpoint does not re-sample the image just because you made it smaller by moving the handles.

Me personnally....I prefer to optimize the images before they every get into powerpoint via (insert > pictures > from
file)

I would add that PP drops them in based on the dpi resolution of the
file, not 1:1 on a pixel basis which would give you the ideal size (some
pictures can generate alot of moiré if you resample just a little).

for a 1024x768 screen, I set the page to 10.24 x 7.68, giving me 100dpi.
once I figure out the size I need I resample it and save it at 100dpi

If you are in a hurry, something like NX Powerlite might work for you. It's
available here: http://www.nxpowerlite.com/

In the future, be sure to have the marketing people, resample the images
before they put them in a presentation, as Taj suggested.

When resampling images it is important change the resolution first, then
change the dimensions. (If it is done in reverse, the size will change
again when the resolution is changed.)

Be sure that the same images are not being placed on many slides
individually. By placing them on slide masters, you can really reduce file
size. Good luck.

Or insert once and then copy and paste as needed. That's one time when
copy/paste of images works well.

final output should be generated by graphics people, you don't know the
size requirements until you layout and test it

depends on the program, high end allow you to set both

I wanted to ask about that, I do that in any case but I was never sure
if it stored one or many copies internally.

In the same vein, how is it stored internally? is a jpeg expanded on
viewing or on insertion? what is the ideal format to insert as a file?
do any allow true transparancy masks,as far as I can tell, png has 1 bit
masks, which is annoying when you switch backgrounds?

PPT 2002 allows multiple masters.
