Try like,
尝试像，
array(
'format' => 'image',
'value'=>function($data) { return $data->imageurl; },
),
And in your model,
在你的模型中，
public function getImageurl()
{
return \Yii::$app->request->BaseUrl.'/<path to image>/'.$this->logo;
}
Don't know this is the right way or not.But this works for me.
不知道这是否正确。但这对我有用。

Yii 2 has built-in helper for building urls. You can bulld the url to image by path too (by passing second parameter $scheme).
Yii 2 具有用于构建 url 的内置帮助程序。您也可以通过路径将 url 扩展为图像（通过传递第二个参数$scheme）。
So I recommend using this:
所以我建议使用这个：
GridView:
网格视图：
use yii\helpers\Url;
[
'format' => 'image',
'value' => function ($model) {
return $model->getImageUrl();
},
],
Model:
模型：
public function getImageUrl()
{
return Url::to('@web/path/to/logo/' . $this->logo, true);
}

In views->image->index.php
在视图->图像->index.php
<?= GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
[
'attribute'=>'image_path',
'label'=>'Image',
'format'=>'html',
'content' => function($data){
$url = $data->getParentName();
return Html::img($url, ['alt'=>'yii','width'=>'250','height'=>'100']);
}
],
'caption1',
'caption2',
'status',
['class' => 'yii\grid\ActionColumn'],
],
'tableOptions' =>['class' => 'table table-striped table-bordered'],
]); ?>
In model->image
在模型->图像中
public function getParent()
{
return $this->hasOne(Image::className(), ['image_id' => 'image_id']);
}
public function getParentName()
{
$model=$this->parent;
return $model?$model->image_path:'';
}
table attributes are, image_id,image_path,caption1,caption2,status
表属性是，image_id,image_path,caption1,caption2,status

I used to use 'raw' format for this type of work.
我曾经为这种类型的工作使用“原始”格式。
[
"attribute": "image",
"format": "raw",
"value": function($model){
return ($model->image) ? Html::img("/path-to-img-location" . $model->image) : false;
}
]
if image exists then image is displayed otherwise it is blank.
如果图像存在，则显示图像，否则为空白。

It is simple you can just declare it in your index file as below.
很简单，您可以在索引文件中声明它，如下所示。
[
'label' => Your Label Here',
'format' => 'raw',
'value' => function ($data) {
$images = '';
$images = $images.Html::img(\Yii::$app->request->BaseUrl.'/your-path-here/'.$date->getImagefilename(),['alt'=>'','width'=>'30','height'=>'30', 'data-toggle'=>'tooltip','data-placement'=>'left','title' => $name->pictogram_comment ,'style'=>'cursor:default;']);
return ($images);
}
],
You will have to get image instance from your model. If required example please comment, will get back on that.
您必须从模型中获取图像实例。如果需要示例，请发表评论，将回复。

You can also use:
您还可以使用：
public function getImageurl()
{
return \Yii::$app->urlManager->createUrl('@web/path/to/logo/'.$this->logo);
}
'@web' is a predefined path aliases.
' @web' 是一个预定义的路径别名。
'urlManager->CreateUrl()'do something more than resolving aliases.
' urlManager->CreateUrl()'做的不仅仅是解析别名。
