Hallo!

Um Bilder aus einem Ordner auf meiner Webseite anzeigen zu lassen benutze ich folgenden Programmcode: ...s.u.
Jetzt möchte ich noch, dass ein Bild welches mit $_width_max_ = 500 auf meinen Seite angezeigt wird, zusätzlich mit einem Link oder so in seiner vollen Größen (also $_width_max_ = 0) auf einen neuen leeren Seite angezeigt wird.

Da ich nicht so erfahren bin, gelingt es mir nicht. Ich hoffe, dass mir einer weiterhelfen kann. :wink:

Gruß, Frank

$_hspace_ = 20 ;
// border of image
$_border_ = 0;

// sorting
// SORT_ASC, SORT_DESC
$_sort_ = SORT_ASC;


// width of full image
// if original width, set this variable to 0
$_width_max_ = 500 ;

// show filename below image
// 1 = YES, 0 = NO

Mister Ad

Hallo noch mal,

Konkret liegt mein Problem darin dass ich eine gesetzte Variable ($_width_max_ = 500) mit dem klick auf einem link verändern ($_width_max_ = 0) möchte, es aber nicht hinbekomme.

Danke und Gruß, Frank.

Machs einfach so
