====== imgx= (Bild aus Dateizentrale) ======

Forum: [[http://forum.phpwcms.org/viewtopic.php?p=112248#p112248]]


Für Bilder gibt es einen speziellen Replacement Tag und in der Dateiverwaltung die einfache ID-Info beim Überfahren der jeweiligen Datei.

 **Bilder:**
<code html>
[img=ID.FORMATxWxHxCROPxQUALITY ALT-Text]TITEL-Text[/img]
</code>

**verkürzt:**
<code html>
[img=ID.FORMATxWxHxCROPxQUALITY]
</code>


Die ''WxHxCROPxQUALITY'' sind optional - ''[W[xH[xCROP[xQUALITY] [Alt-Text]]]]''

Im Prinzip reicht das:

<code html>
[img=10x100x100]
</code>
Zeige Bild mit ID 10 als JPG und verkleinere proportional auf max. 100 Pixel Breite bzw. 100 Pixel Höhe.

**Downloads:**
<code html>
    [download=ID1]
</code>

<code html>
    [download=ID1]Caption[/download]
</code>

<code html>
    [download=ID1,ID2,ID3]Caption1
    Caption2
    Caption3[/download]
</code>


===== Tag [imgx=.....] - wird nicht mehr gebraucht =====

<del>Die interne Funktion mit -- //[img=ID.FORMAT WxHxCROPxQUALITY]Title-Text[/imgx]// -- funktioniert noch nicht (Stand v1.4.0 r286), deshalb wurde die Prozedur von mir temporär nach frontend_render ausgelagert ( /include/inc_front/ext.func.inc.php ->function parse_images($matches) ).</del>

   Have a look into /include/inc_front/ext.func.inc.php ->    function parse_images($matches) { ....
   For me it can´t run.
   I have swaped out and patched this function to /frontend_render/ with the tag:
   [imgx=ID.FORMAT WxHxCROPxQUALITY ALT-Text]Title-Text[/imgx]
