PHP Hilfe bei style="background:url..." code

Hallo ich habe ein Problem, was ich irgendwie nicht auf die Reihe bekomme. Und zwar geht es um die Seite test5.pagewerbung.de/wiese

die seite bin ich gerade am entwickeln, doch eine sache stört mich noch. unter der slideshow befindet sich der orange balken, mit vorschaubilder. allerdings sind die gewählten ausschnitte eher ungünstig und nichtssagend. ich poste euch mal den code, es dreht sich, so wie ich den code verstehe um die zeile 172.

das was ich gerne machen würde: die bilder, die in dem ausgewählten ausschnitt angezeigt werden verkleiner o.ä.

danke schonmal für hilfe/vorschläge

Hi, du könntest die Bilder hier anstatt als Backgroundimg

Code:

<span class="slide_img" style="background:url(<?php if(isset($img_url) && $img_url != "") echo $slideYoumania['img_out2'] ?> ) no-repeat left 50% ;"></span>

als 'normales' Image einbauen und auf 170x90 runterskalieren.
(wieso eigentlich isset($img_url) ? Wenn dann doch if (isset($slideYoumania['img_out2'])) ...
aber egal)

Oder Du legst in /images/stories/slider/ jeweils noch ein
manuell erstelltes Thumbnail rein und benamst es als *_thumb.*, z.B.:
TGA_Foto_rdax_358x268_thumb.png.

Dann noch die Thumb-Url in der foreach-Schleife oben mitgeben:

Code:

foreach ( $load_items as $row ) {
$img_url = youmania_image($row);
$tmp = pathinfo($img_url);
$img_thumb_url = $tmp['filename'].'_thumb.'.$tmp['extension'];
$slideYoumania = array(
'date' => JHTML::_('date', $row->created, '%d-%m-%Y'),
'intro' => substr(strip_tags($row->introtext,'<a><span>'),0,$chars),
'intro2' => substr(strip_tags($row->introtext),0,15),
'link' => ContentHelperRoute::getArticleRoute($row->slug, $row->catslug, $row->sectionid),
'cat_link' => ContentHelperRoute::getCategoryRoute($row->catid, $row->sectionid),
'img_url' => $img_url,
'title' => $row->title,
'cat_title' => $row->cattitle,
'img_url' => '',
'img_out' => "<img src=\"".JURI::base().$img_url."\" border=\"0\" class=\"YJYoumania_link\" title=\"".$row->cattitle." :: ".$row->title."\" alt=\"\"/>",
'img_out2'=> "".JURI::base().$img_url."",
'img_out3'=> JURI::base().$img_thumb_url
);
$slidesYoumania[] = $slideYoumania;
}

und unten im 'slide_img' dieses Thumb ($slideYoumania['img_out3']) ausgeben.
