This is a "Quick and Dirty" way to have a full browser background image in your exhibits...
For Indexhibit version 2:
--------------------------------------------------------
From the backend go to Admin -> Assets -> plugin.backgrounder.php
Find line:
$style .= ($OBJ->vars->exhibit['bgimg'] != '') ? "\nbackground-image: url(" . $OBJ->baseurl . "/files/" . $OBJ->vars->exhibit['bgimg'] . ");\nbackground-repeat: $tiling;\nbackground-position: 215px 0;\nbackground-attachment: fixed;\n" : '';
and change it to:
$style .= ($OBJ->vars->exhibit['bgimg'] != '') ? "\nbackground: url(" . $OBJ->baseurl . "/files/" . $OBJ->vars->exhibit['bgimg'] . ") no-repeat center center fixed;\n-moz-background-size: cover;\n-webkit-background-size: cover;\n-o-background-size: cover;\nbackground-size: cover;\n" : '';
Click the Disk/Save icon.
For Indexhibit version 0.73 or older:
--------------------------------------------------------
Open the index.php file found in ndxz-studio -> site -> plugin
Find line 210
$style .= ($img != '') ? "\nbackground-image: url(".BASEURL."/files/$img);\nbackground-repeat: $tile;\nbackground-position: 215px 0;\nbackground-attachment: fixed;\n" : '';
and change it to
$style .= ($img != '') ? "\nbackground: url(".BASEURL."/files/$img) no-repeat center center fixed;\n-moz-background-size: cover;\n-webkit-background-size: cover;\n-o-background-size: cover;\nbackground-size: cover;\n" : '';
Save.
* Internet Explorer doesn’t recognize the CSS3 property of background-size below IE9. Modern browsers are good though.
