Inserting Large Images

[Dennis Hughes]

I'm new to PowerPoint, as you will read.

I'm making a ppt 2003 presentation for our group and inserting a number of
2k x 3k images into the slides. One image per slide. The ppt file size is
now 90 MB, which is going to be a pain to email.

To make the images fit the slide, I formatted the slide (or is it the
image?), changed the scale height/width % to 28% and then fine tuned the
resize by dragging the corner.

How do I get rid of the excess pixels that are causing such a large file
size? What is the normal ppt slide size in inches? Do I need to resize in
Photoshop first?

Thanks for the help,

Dennis

As far as image size, your best bet is probably to resize your pictures
in PowerPoint to be 1024 x 768 pixels (or whatever your screen resolution
is). Don't deal with inches; inches are meaningless. Once you have the
pictures sized appropriately, be sure that you are using Insert > Picture

From File to insert the pictures and not copying and pasting them into

PowerPoint.

Because you are inserting pictures one per slide, you might benefit from:

This might help you get the pictures into PowerPoint more easily.

Dennis,

2 to 3 K per image is pretty small and I doubt your going to reduce it much.

I thought he was saying 2000 pixels by 3000 pixels, not around 2 or 3
kilobytes in size. If, indeed, it was the latter, then he is either
inserting a whole lot of pictures or he is copying and pasting the
pictures to get a 90MB file size.

The original image size is 2000 px by 3008 px.

I'm bring the images into PowerPoint by using Insert Picture from File.

I don't see a place in the format (which I open by right clicking on the
image) to change the pixel size to 1024 px by 768 px.

I'll read the links. That may help.

Thanks,

Dennis

I disagree on your "inches are meaningless" statement. Because the
PowerPoint slides are set up with a default size of 10 1/2" wide by 7
1/2" tall, it is far easier to get your picture sizes correct "by the
inches." Pixel sizes are not useful when you are both presenting the
slide and printing it. The higher the pixel resolution, the larger the
image size becomes.

No matter what the screen resolution is, once you have a slide size set
with a fixed inch measurement, it won't matter when the resolution of
the screen changes. Let's make the assumption that you do create the
slide size @ 1024 x 768. If you make the presentation on a screen
whose resolution is different, you will have problems.

That's true, but if you make the picture 10 1/2" by 7 1/2", it is still
saved as a certain number of pixels that depends entirely on the
resolution you save it at. If that is 300dpi, then you have a picture
that is 3150 x 2250 pixels (too big for most computers). If that is 72
dpi, then you end up with 756 x 540 pixels (too small for most
computers). In the end, anything for the screen is measured in pixels.

What DOES happen is, that although the # of pixels stays the same, and
this is less so obvious, is that the pixel SIZE is changing, while the #
of pixels stays the same.

Yes, that is why inches are meaningless. If you project your picture on
an 8 foot by 6 foot wall, you will have much larger pixels than if you
show it on your 16 inch by 12 inch screen, but if the computer can only
handle a resolution of 1024 x 768, you won't get a better quality image
when you project a "bigger" picture on the hugh jwall. That is, there is
no reason to save the picture as 8 foot by 6 foot just because you are
projecting it on an 8 foot by 6 foot wall.

I've spent some time researching the good links and info provided here. All
is appreciated.

Here is what I have found inside the PowerPoint2003 application:
Click on the image and the handles will appear
Select the crop icon from the Picture toolbar ( I can't find it as a command
in the Menus)
Make your crop
Right click on the image and go to Format Image or use the Format menu and
select Picture
In the Format Picture dialogue box select the picture tab. (I've worked
with the size tab before)
Click the Compress button and a Compress Picture dialogue box will appear.
In the Change Resolution select the Web Screen radio button. It will give
you 96 dpi (I know that's not ppi, but in this case, it might be the same.
In options check both boxes - Compress pictures and delete cropped area of
pictures.

The dirty deed is done and the file size went from 90 MB to 12.6 MB.

One of a few ways to get there.

Thanks,

Dennis

That's a very good summary, Dennis. Thank you.

Also, you can choose to compress all the pix in the presentation at once.
Might save you some time.

Oh, and you're right -- DPI is the same as PPI in this dialog. I think it's
because the Print option lists 200 dpi (which makes sense), and I guess MS
figured having PPI in the web/screen setting would cause more people to
question it than if they just said DPI.

What image editing software you have there used to resize?
What picture format or are they all in .jpeg, jpg or jpe?
You can use 450px by 294 px @ 72 pixels/inch of Resolution for 800 by 600 monitor
screen viewing and for Email BUT not so good for printing those slides.
