There appears to be some confusion here. When you hear "vertical line" on that page, VoiceOver is not reading images but reading plain text. A vertical line character is used to visually separate the links (much as a comma could be used to separate list items): http://en.wikipedia.org/wiki/Pipe_(character) For what it's worth, better modern practice would be to use HTML list markup and draw the lines between list items using CSS borders or background-images (which would never be read). Example implementations: http://css.maxdesign.com.au/listamatic/horizontal16.htm http://css.maxdesign.com.au/listamatic/horizontal32.htm http://css.maxdesign.com.au/listamatic/horizontal36.htm > And when I read this site on a pc using a screen reader, the vertical lines > are nowhere to be heard. I suspect this reflects differing character-level verbosity settings between your PC screen reader and VoiceOver. > So with that long explanation, can somebody please clarify for me what the > image navigation in vo is all about? Well, if I understand your email correctly, you expected it to change how VoiceOver reads through a page. But the VoiceOver Help about the feature suggests that setting should only affect which images are included in the pop-up VoiceOver menu (by which I think they mean the Item Chooser menu accessed with VO-I): > Choose how you want VoiceOver to navigate images from the pop-up menu: Never, > With Descriptions, Always. > By default, VoiceOver navigates only to images that contain a description, > called "alt text." This option is useful because many websites use images for > links. So with "Never" set, I'd expect no images to be included in the menu, with "With Descriptions" set I'd expect only images with "alt" text specified to be included, and with "Always" I'd expect every image on the page to be included.
