I posted this question in 2020. Its still unresolved. Does anyone know how to bring in an updated image into Keynote (which I've previously placed and masked in Keynote) so that its replaces it exactly? When I bring the updated image back into Keynote it comes in at a reduced size. How do I get Keynote to replace the image and keep it the same size as before?
iMac 24″, macOS 11.6
Instead of using Keynote to perform the masking, I prefer using a dedicated image editing application to do all the retouching. It’s a quicker and simpler method than using Keynote and achieves a pixel to pixel accurate image in Keynote.
Try the workaround:
1
Before using Keynote, edit the original image in your image editing application for colour correction, levels, contrast, also crop the image in this stage, instead of masking in Keynote.
The inbuilt Mac Preview application works perfectly for this, or use your regular software; Photoshop, Pixelmator, Affinity etc
Save As a new image file with a new name
2
Insert the cropped image file on to a slide in Keynote and size and position it. (No masking required)
Select the image on the slide and define as a Media placeholder:
Format > Advanced > Define as Media Placeholder
Save As a new Keynote file and play
3
When changes are required to the same image, open the cropped image in your image edging application and make the required changes for colour correction, levels, contrast.
Save As a new file with a new name
4
Using the Finder, drag the edited image file directly onto the media placeholder on the slide.
Save As a new Keynote file and Play

Option click on the image to Reset Mask. Then go to replace image in the image palette. It should replace it at the current size. You'll have to remake the mask afterwards.
Hello richardesigner,

Hi Gary,
Thanks for taking the time to write and explain your work around. Its good, but unfortunately the sizing takes place in Keynote. With multiple images constantly being cropped and re-sized (think mood boards) going backwards and forwards from Keynote to Photoshop would just be too time consuming. Esp resizing an image in Photoshop and then re-importing it into Keynote and then probably re-sizing is again. The images within the masks, will probably need updating in the future. As all Adobe Illustrator and Indesign users will know this is usually a simple matter of alt clicking an image, having it open in Photoshop, resaving it and then it auto updating in Illustrator. Much simpler and quicker. Maybe Apple can't use this type of process. Perhaps its an Adobe copyrighted procedure?
Thanks, but that link doesn't answer my question.
