Answer 1

You should fix form enctype, use multipart/form-data instead of multipart/form- data.
You could use CMultiFileUpload
controller:
$images = CUploadedFile::getInstancesByName('image');
foreach ($images as $image => $pic) {
}
view:
$this->widget('CMultiFileUpload', array(
'name' => 'image',
'accept' => 'jpeg|jpg|gif|png',
'duplicate' => 'Duplicate file!',
'denied' => 'Invalid file type',
));
Add to model 'maxFiles' param, if you need validation to work properly for multifiles upload.
public function rules()
{
return array(
array('image', 'file', 'types'=>'jpg,gif,png', 'maxSize'=>'204800', 'allowEmpty'=>true, 'maxFiles'=>4),
);
}
