你可以轻松实现这个目标。

Primiraly我可以向你推荐例如，将图像上传到ASP.WEB API Rest HTTP-service，将它存储在一些内存缓存中，然后你可以借助jQuery Ajax将新上传的图像预览到某个UI容器（web部分），并且只有在一些协议操作之后才将它提交给DB。

Hi , of courese you can easily achive this.
Primiraly I can propose to you to upload image, for example, to ASP.WEB API Rest HTTP-service , store it in some in-memory cache, then you can preview newly uploaded image with help of jQuery Ajax to some UI container(web part), and only after some agreement operation submit it to the DB.
