SmartFrames have full-screen viewing enabled as standard.
Viewers can activate this by clicking on the full-screen button that sits in the top-right-hand corner of SmartFrame images. You can try this on the SmartFrame below.
Should the image within the SmartFrame be too low in resolution to satisfy the full dimensions of the display on which it is viewed, it will simply appear at its maximum resolution when the full-screen viewing option is activated. This is because, in order to preserve the quality of your images, SmartFrame does not upscale them.
SmartFrames displayed on mobile and tablet devices can be viewed in a Full-window mode. This works in a similar way to the Full-screen mode, with the SmartFrame occupying the entirety of the browser tab in which it’s displayed. To activate the Full-window mode, simply double-tap on the SmartFrame, or tap on the Full-window icon in the upper-right-hand corner of the frame.
