image identifier, using builtin images, how kvirc locates image files
600
Semantics of the <image_id> parameter
602
Some KVIrc commands and functions accept
603
the <image_id> as a parameter.
604
The <image_id> indicates an image to be displayed
605
by some gui element. Since KVIrc has a set of
606
builtin icons, we want the user to be able to use it :).[br]
607
The <image_id> can be either a signed integer number
609
If it is a signed integer it is interpreted as
610
index of the internal KVIrc image to use:
611
positive integers (starting at 0) indicate
612
small (16x16) icons (the ones used in the view widget).[br]
613
If <image_id> is anything else than a signed integer,
614
it is interpreted as a filename.
615
The filename can be an absolute file path or a relative one.
616
In this last case KVIrc will look for the file in a predefined set
617
of directories: First in the local "pics" directory (usually
618
in ~/kvirc-version/pics/), then in the local "incoming" directory,
619
then in the global "pics" directory , then in the user home (~)
620
and in the current directory.[br]
