Add an image in Keynote on Mac
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 iPhone or iPad.
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. 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.
Click to 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.
Click the image to select it, then choose Format > Advanced > Define as Media Placeholder (from the Format menu at the top of your screen).
Take a photo or scan with iPhone or iPad and add it to a presentation
If you have your iPhone or iPad nearby, you can use it to take a photo or scan and insert the image directly into a presentation on your Mac.
Note: To make sure your Mac, iPhone, or iPad supports this feature, see the Apple Support article System requirements for Continuity.
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 iPhone or iPad, 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.
Click the image to select it, then in the Format sidebar, click the Image tab.
Click the Description text box, then enter your text.
If you export your presentation as a PDF, image descriptions are still readable by assistive technology. See Export to PowerPoint or another file format in Keynote on Mac.
To add descriptions to the images in an image gallery, see Add an image gallery in Keynote on Mac. To add a caption to your image, see Add a caption or title to objects in Keynote on Mac.
To work with multiple images at the same time, hold down the Shift key while you click the images.
