Add or replace images in Keynote for iCloud
You can add images (photos) to your presentation, as well as replace placeholder images in a theme. You can also add an image description that can be read by assistive technology (for example, VoiceOver).
Add an image
Click the Media button in the toolbar, click Image, browse to find the image you want to use, then double-click it.
You can also drag an image from your computer to the slide, or copy and paste it.
To reposition the image, drag it to a new location.
You can use alignment guides to help you position an object more precisely.
To customize the look of the image, select the image, click Style at the top of the Format sidebar, then make your choices.
For example, you can add a border or shadow to the image. See Customize the look of objects in Keynote for iCloud.
Replace an image
Select the image that you want to replace.
Click Image at the top of the Format sidebar on the right, then click Replace.
Browse to choose a new image, then double-click it.
You can also drag an image from your computer to an image you want to replace, and when the blue outline appears around the image, release the mouse button. (If you drop outside the blue outline, the new image is added to the slide instead of replacing the existing image.)
To delete an image, select it, then press Delete.
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 in your presentation.
Select an image in your presentation, then click Image at the top of the Format sidebar.
Click the Description text box, then enter your text.
To delete an image (or any other type of object), select it, then press Delete.
