Use VoiceOver to navigate web pages by images or frames on Mac
Note: VO represents the VoiceOver modifier that you press with additional keys to enter VoiceOver commands. By default, you can press Control and Option together or just press Caps Lock.
Images
Move to the next image: Press VO-Command-G.
Move to the previous image: Press VO-Command-Shift-G.
To specify when to navigate to images, open VoiceOver Utility (press VO-Fn-F8 when VoiceOver is on), click the Web category, then click the Navigate Images pop-up menu.
If an image doesn’t have a description, VoiceOver speaks the image filename. You can create a custom label for these images, or for images whose alt text isn’t useful.
If you enabled image descriptions in the VoiceOver Recognition category in VoiceOver Utility, you can press VO-Shift-L to have VoiceOver use on-device intelligence to describe images on websites to improve accessibility.
Frames
If a web page organises information into areas called frames, you can use them to navigate the page.
Move to the next frame: Press VO-Command-F.
Move to the previous frame: Press VO-Command-Shift-F.
If images or frames are listed in the VoiceOver rotor when viewing web pages, you can use it to move to a specific image or frame. See Use the VoiceOver rotor.
