This is not a bug in 4images itself, rather its a work around a bug in some PHP versions (not all versions have this bug), so if your RSS feed passes validation, you should not apply this patch.
(you can check if your RSS feed is valid at
http://feedvalidator.org)
Step 1In
rss.php find
'type' => mime_content_type($file),
Replace with:
'type' => get_mime_content_type($file),
Step 2In
includes/functions.php at the end, above closing
?> insert:
function get_mime_content_type($file) {
if (function_exists('mime_content_type')) {
$type = mime_content_type($file);
if ($type) {
return $type;
}
}
$info = @getimagesize($file);
if (isset($info['mime'])) {
return $info['mime'];
}
$type = @exec(trim('file -bi '.escapeshellarg($file)));
if (strpos($type, ';') !== false) {
list($type) = explode(';', $type);
}
if ($type) {
return $type;
}
