Anchorage

Anchorage - In magazines, images will be anchored by captions (directly explaining what pictures depict) by cover lines, or by articles and headlines. Anchoring an image helps give it a meaning, as it helps the reader understand the significance.

Secondary Images - They nay be used on the front cover to help promote other features in the magazine, usually anchored by a cover line.
They are often used in magazines where reader's need to be enticed by the picture rather than the cover line text. (e.g celebrity magazine)

Coverlines -  These are located at various points on the front cover, telling readers about the magazine's contents - and specifically, the articles they will find.
The front cover often features 6-12 coverlines in an attempt to lure different readers to different things.
Coverlines will often use language and presentational devices to be most effective.
