Editing Image server (section)

=== E-commerce ===

The simplest product viewers usually require at least 3 versions of an image: a 100x100 thumbnail, a 400x300 medium 'in-page, selected', and a 1200x900 'zoomed' version. Combined with the original file, this results in 4 separate images that must be stored, updated, and linked to.

In [[e-commerce]], image servers are qualified by their abilities to scale to hundreds of thousands of images, to multiple [[Central processing unit|CPUs]] or [[Load balancing (computing)|load-balanced]] [[Server (computing)|server]] machines, and to the quantity and quality of their image processing functionalities, such as resizing, compositing, zoom and 3D viewers, and the addition of dynamic data to the images in the form of overlaid text or graphics.

Dynamic compositing is also extremely useful for merchants who permit product customization. Many vehicle manufacturers use dynamic compositing to let the visitor visualize their customizations.
