    Image Component

    The Image component allows a single image asset to be displayed on the page. Images are adaptive; the relevant image width is selected for the screen size.

     

    Images must be uploaded to an Assets folder in advance – they cannot be uploaded through the Image component. Check out the Navigating AEM guide for more info.

    Sizing

    Below are guidelines detailing the minimum recommended sizing specs across our various available aspect ratios. Within our components, the most commonly applied ratios are 16:9, 4:3, and 1:1. Oher common sizes are 32:9, 3:2, 2:3 and 3:4. When cropping images (before uploading to AEM), size to these ratios.

    Accessibility

    1. When adding an Image to the page, make sure to add alternative text that describes the information or function represented by the photo, unless it is decorative. This will be read out by a screen reader for users who cannot view the image.

    a. Check out the Image Description Best Practices guide for editorial guidance on writing useful alternative text.

    Other tips

    1. Use the Emulator widget to test Image size on different devices.
    2. The recommended character limit for captions is 40 characters.
    3. If authored/pulled from the DAM, a caption appears below the Image. Make sure the "Caption" field in Metadata tab is empty if none should display.
