Busca esto en ese archivo:
array(
'tag' => 'img',
'type' => 'unparsed_content',
'parameters' => array(
'alt' => array('optional' => true),
'width' => array('optional' => true, 'value' => ' width="$1"', 'match' => '(\d+)'),
'height' => array('optional' => true, 'value' => ' height="$1"', 'match' => '(\d+)'),
),
'content' => !empty($adkportal['enable_watermark']) ? '<img src="'.$boardurl.'/adkportal/sw.php?sw=$1" alt="{alt}"{width}{height} class="bbc_img resized" />' : '<img src="$1" alt="{alt}"{width}{height} class="bbc_img resized" />',
'validate' => create_function('&$tag, &$data, $disabled', '
$data = strtr($data, array(\'<br />\' => \'\'));
if (strpos($data, \'http://\') !== 0 && strpos($data, \'https://\') !== 0)
$data = \'http://\' . $data;
'),
'disabled_content' => '($1)',
),
array(
'tag' => 'img',
'type' => 'unparsed_content',
'content' => !empty($adkportal['enable_watermark']) ? '<img src="'.$boardurl.'/adkportal/sw.php?sw=$1" alt="" class="bbc_img" />' : '<img src="$1" alt="" class="bbc_img" />',
'validate' => create_function('&$tag, &$data, $disabled', '
$data = strtr($data, array(\'<br />\' => \'\'));
if (strpos($data, \'http://\') !== 0 && strpos($data, \'https://\') !== 0)
$data = \'http://\' . $data;
'),
'disabled_content' => '($1)',
),
Y reemplazalo por esto:
array(
'tag' => 'img',
'type' => 'unparsed_content',
'parameters' => array(
'alt' => array('optional' => true),
'width' => array('optional' => true, 'value' => ' width="$1"', 'match' => '(\d+)'),
'height' => array('optional' => true, 'value' => ' height="$1"', 'match' => '(\d+)'),
),
'content' => '<img src="$1" alt="{alt}"{width}{height} border="0" onload="NcodeImageResizer.createOn(this);" class="bbc_img" />',
'validate' => create_function('&$tag, &$data, $disabled', '$data = strtr($data, array(\'<br />\' => \'\'));'),
'disabled_content' => '($1)',
),
array(
'tag' => 'img',
'type' => 'unparsed_content',
'content' => '<img src="$1" alt="" border="0" onload="NcodeImageResizer.createOn(this);" class="bbc_img" />',
'validate' => create_function('&$tag, &$data, $disabled', '$data = strtr($data, array(\'<br />\' => \'\'));'),
'disabled_content' => '($1)',
),
Obviamente recuerda hacer backup del archivo!
