Zooming in

Enlarging images to provide visitors with more detail.

Problem

A computer monitor has low resolution, which can make detail difficult to see.

Solution

Allow visitors to zoom into an image using one of the following methods:

  1. An enlarge button. An easy method is to put a small “Enlarge” button next to an image. In current screen displays, zoomed images that fit within 750 pixels wide and 650 pixels high, are sufficient.
  2. Zoom into and around details. Provide a small thumbnail that the user can click on and see what they are looking at in detail. Also, let the visitor pan from within the zoomed view.

Discussion

Zooming is critical, so virtually all images on your web site should be displayed relatively small inline with the text, but have an option for a full-screen view. It is rare that visitors really need to zoom far into an image, so an enlarge button with one state of zoom will suffice in most instances.

Organizations concerned with the copyrights of their images can either watermark them with a faint tint (a watermark with curved lines, using both white and black, is virtually impossible to manually remove), or by slightly warping the zoomed image so that the high-resolution original cannot be re-assembled.
