Name

no_image_rewrite — prevent image locations from being altered

VALUE

0 | 1

DEFAULT

0

DESCRIPTION

This pragma prevents image locations in Interchange pages from being altered.

Interchange normally rewrites image locations to point to ImageDir (or ImageDirSecure). This applies to image locations mentioned in <img src="">, <input src="">, <body background="">, <table background=""> and table subelements (<th>, <tr> and <td>).

EXAMPLES

Example: Image path rewriting example

If the no_image_rewrite pragma is disabled and ImageDir is set to "/standard/images", an image URL like:

<img src="fancy.gif">

would be changed to:

<img src="/standard/images/fancy.gif">

With the directive enabled, the image URLs would be left intact.
