Keynote for Mac: Add images in Keynote
You can add photos and graphics to any slide and replace media placeholders with your own images. You can add photos from a photo library, drag them from a website or from the Finder, or take a photo on a nearby iOS device.
Add or replace an image
Do any of the following:
Drag an image from your computer or a webpage to a media placeholder or anywhere else on the slide or the workspace around it. (For more information about expanding your workspace, see Add workspace around a slide.)
Click in the bottom-right corner of a media placeholder, then select an image from a photo library.
Click in the toolbar, choose Photos, then drag an image from a photo library to the slide or to a media placeholder.
To search for an image, click the magnifying glass in the upper-right corner of the media window.
Select the image you want to replace, then in the Format sidebar, click the Image tab. Click Replace, then choose an image. The new image retains the dimensions of the original.
If you can’t replace an image on a slide, the image may be locked or grouped.
Create a media placeholder
You can add a media placeholder (to which you can add an image, video, or audio file) to a presentation. Using a media placeholder lets you easily replace media without disturbing other elements on the slide.
Add an image to your slide, then format it the way you want your presentation’s images to look.
You can add a mask, add a border, rotate the image, change its size, and more.
Select the image, then choose Format > Advanced > Define as Media Placeholder (from the Format menu at the top of your screen).
Take a photo or scan with an iOS device and add it to a presentation
If you have an iOS device nearby, you can use it to take a photo or scan and insert it directly into a presentation on your Mac.
Note: To make sure you can do this with your Mac and iOS device, see the Apple Support article System requirements for Continuity on Mac, iPhone, iPad, iPod touch, and Apple Watch.
On the slide where you want to add the photo or scan, click in the toolbar, then choose Take Photo or Scan Documents below your device name.
On your iOS device, do one of the following:
Take a photo: Tap , then tap Use Photo (tap Retake to retake the photo).
Scan a document automatically: Position the document in view of the camera to automatically capture the page, crop it, and correct its perspective. To insert the scan in your presentation, tap Save.
Scan a page manually: Tap , then drag the frame to adjust the area you want to scan. Tap Keep Scan, then tap Save.
Drag the image to move it, or drag any selection handle to resize it on your slide.
Note: If you scan more than one item, only the first one appears in your presentation.
Add an image description
You can add a description to any image in your presentation. Image descriptions are read by assistive technology (for example, VoiceOver) when someone uses that technology to access your presentation. Image descriptions aren’t visible anywhere in your presentation.
Select the image, then, in the Format sidebar, click the Image tab.
Click the Description text box, then enter your text.
To add descriptions to the images in an image gallery, see Add an image gallery.
To add a caption to your image, see Create a caption for an image or other object.
