The Images section, is where the entire list of all the images used in Virtual Spaces 2.0 either for a Space, a Slide or as a Link Image is displayed.
Clicking on the "Images" link in the menu will take you to the Image management page.
From here you can either click on an image to modify its name on the next page or add tags to an image indicating its usage either as a Space Background Image, or Slide Image or a Link Image using the dropdown option.
