How to implement cache for images using .net core?

I want to cache my images and found something like this

<cache enabled="true"> Current Time Inside Cache Tag Helper: @DateTime.Now </cache>

Caching for images is client cache and you should configure your app like below: 

app.UseStaticFiles(new StaticFileOptions
            {
                ServeUnknownFileTypes = false,
                OnPrepareResponse = ctx =>
                {
                    const int durationInSeconds = 60 * 60 * 24;
                    ctx.Context.Response.Headers[HeaderNames.CacheControl] = "public,max-age=" + durationInSeconds;
                    ctx.Context.Response.Headers[HeaderNames.Expires] = new[] { DateTime.UtcNow.AddYears(1).ToString("R") }; // Format RFC1123
                }
            });
