ImageDir — specify base location for all image files
ImageDir
is one of quite basic settings in every catalog.cfg
.
The directive specifies a base location, accessible over the web, where Interchange should look for image files, when just relative image filename is given. Automatically "translated" are image locations mentioned in <img src="">, <input src="">, <body background="">, <table background=""> and table subelements (<th>, <tr> and <td>).
A setting of ImageDir
/images/
and a specification
of <img src="test/test.png">
would be
translated to <img src="/images/test/test.png">
