trim() expects parameter 1 to be string - php

Question

Got a situation with image import process, before asking here of course - tried many ways to solve it by myself, but without any luck yet.
I'm getting error in model file: trim() expects parameter 1 to be string, array given in file /.../file.php on line 3875. Have to mention that - when there's single image - importing that perfectly, as soon as getting multiple images (more than one) - getting this error, and doesn't importing any image, just skipping.
Line 387: $image = trim($image);
Whole function code:
protected function imageHandler($field, &$config, $multiple = false, $item_id = NULL) {
$image_array = array();
if (empty($config['columns'][$field])) {
if ($multiple) {
return $image_array;
} else {
return '';
}
}
$sort_order = 0;
foreach ((array) $config['columns'][$field] as $images) {
if (!empty($config['multiple_separator']) && is_string($images)) {
$images = explode(#html_entity_decode($config['multiple_separator']), $images);
}
//is_array($images) && reset($images);
if ($multiple && is_array($images) && $config['columns']['image'] == $images[key($images)]) {
array_shift($images);
}
foreach ((array) $images as $image) {
$image = trim($image);
if ($config['image_download'] && $image) {
// if (substr($image, 0, 2) == '//') {
// $image = 'http:' . $image;
// }
$file_info = pathinfo(parse_url(trim($image), PHP_URL_PATH));
// if no extension, get it by mime
if (empty($file_info['extension'])) {
$ch = curl_init();

Tried to use return $image; after that line, even that didn't helped. Was trying to find similar problem to this one to find a solution without posting here, but seems like I won't move anywhere withou help. Thanks in advance!
