@title: The image viewer plugin
1340
Adds a simple internal image viewer to KVIrc.<br>
1341
You can view images by using the command<br>
1342
<b>/image [filename]</b><br>
1343
Filename must be an absolute file path.<br>
1344
If no filename is specified , a "file open" dialog
1345
will be shown to allow selecting a file.<br>
1346
The image types supported are depending on
1347
the underlying Qt and compilation options.<br>
1348
Generally, bmp, png, pnm and xpm are available.<br>
1349
If KVIrc has been compiled with the jpeg support, that
1350
format will be also viewable.<br>
1351
You can use the viewer as the default "player"
1352
of images (see <a href="play.kvihelp">PLAY</a>).<br>
1353
In order to do so , put "IMAGE <a href="s_execfilename.kvihelp">$execFileName</a>" in the
1354
"Run script" field (misc options dialog , mimetypes tab)
1355
for the mimetypes that you want to play with the viewer.<br>
1357
If you unload the plugin , the /IMAGE command will no longer work.<br>
1358
Here comes a simple workaround "commandline field" script for this problem:<br>
1359
Version 1: Use the plugin if is loaded.<br>
1360
<b><a href="if.kvihelp">if</a>(<a href="s_pluginLoaded.kvihelp">$pluginLoaded</a>(image))image <a href="s_execfilename.kvihelp">$ExecFileName</a>; else <a href="exec.kvihelp">exec</a> -q myviewer <a href="s_execfilename.kvihelp">$ExecFileName</a></b><br>
1361
Workaround 2: Use the plugin always, if it is not loaded , load it.<br>
1362
<b><a href="if.kvihelp">if</a>(!<a href="s_pluginloaded.kvihelp">$pluginLoaded</a>(image))<a href="plugin.kvihelp">PLUGIN</a> load libkviimage.so; image <a href="s_execfilename.kvihelp">$ExecFileName</a></b><br>
