Mouse Right-click setting help

This is regarding view posted photo in 文学城.
When I right-click on the posted picture at my office computer (with regular IE in WindowsXP), I can see the "Properties" command at the bottom of the pop-up dialog box, through which the full URL of the picture can be found. However, I don't know why I would get different Dialog box using my home computer where the commad "Add Bookmark" is at the bottom. Does any one know how to change this setting some where in IE such that I can see the URL? I suspect this may be due to my recent change over to Yahoo DSL.
Thank you in advance.
