How to find original photos I used in keynote?

I created a Keynote presentation. About 20 slides with about 2 dozen photos. When I exported the file as a PDF to be emailed it was over 70mb in size. Too large to email.

So, I need to reduce each photo's file size from 3-4 mb each down to 400 kb. But the originals are all over in my 20,000 photo library.

Is there an easy way to gather/package all the images like one can do in Adobe InDesign? I see no linking feature that would help. Suggestions? :-)

To maintain the original file size and image quality, instead of email use a file transfer service such as Dropbox https://www.dropbox.com/
Export the photos from Keynote: File > Export > Images then select either PNG, JPG or TIFF, The file size will be decreased by about 50%
Make a copy of the images contained in Keynote:

Create a new empty folder on the desktop

Open the Keynote project file then go to File > Advanced > Change Filetype > Package

Save the Keynote file

Right Click the Keynote file and select Show package contents

Open the Data Folder and copy all the image files that have the name as the original images

Paste these images into the new folder on the desktop

Your recipients don't need to know how Dropbox works and they don't need a Dropbox account.

You instruct dropbox to send a link to your recipients of the images you want to share, the recipients click the link in the email they receive and it downloads to their computer.

Q1

When exported from Keynote, the JPEG will print better as it is an exact copy of the original, the PDF is is a compressed [lower resolution] version of the original.

Q2

The easy way to identify the images that have to be copied is to select each image in turn in the Data folder finder will display the file information, no need to open the image in Preview,

1 - the images will have the original file name

2 - the file size will be the same as the original, the file size will be shown in beside the file name:

3 - it will not be labeled "small"

Example from the Data folder

Q3

You save a copy of the images from the DATA folder, then use the copied images to send out to your recipients

You must not place these images back in Keynote in any way, you would just be going round in circles and you would corrupt the Keynote file in doing so.

Much thanks for that answer. That would be extremely helpful. I hope I can make this work, but I still am a bit confused. Please clarify for me...

I won't use Dropbox as some recipients won't know how to use that or don't have an account. A final KN PDF file in an email would be best. I started to change some of the 22 photos to a lower resolution size. That reduced the total KN file size from 77 mb to 24 mb. Still too large which is why I'd like to do what you suggested.

Q1. If I export them as JPG vs PNG, would the KN file with photos PRINT better as a PDF, so recipients can use a hard copy?

Q2. When I opened the Data Folder there were files names with added digits in the title. I have to open each one to confirm what the image is. Some seem to be duplicates such as “IMG4964” (197 kb) and “IMG4964-small-321.jpg” (16 kb). Do I keep them all? (I may have screwed this up by trying this several times?)

Q3. I’ve saved the medium sized image files from the DATA folder and copied them to a folder on the desktop. Now what to do? Do I have to insert them individually into the KN file to replace the larger images? Or is there some kind of batch method of doing this?
