I upload a picture in yii2 does not show?

Question

Yii

The problem is that I wrote the code in yii2, uploads it to the database, writes it, creates a folder and puts the saved image there, but it doesn’t show me, and when I look in the browser, look at the code, it shows me this
view?id=12:111 GET zakaz/admin/product/upload/store %5CProducts/Produc... 404 (Not Found)
