Below is a demo to use session to pass the string to appear in _layout page in every page , you can refer to it.

1.Register IHttpContextAccessor and session in Program.cs

builder.Services.AddSession();
builder.Services.AddHttpContextAccessor();
...
app.UseSession();

2.In the controller, set a session variable:

HttpContext.Session.SetString("Photo", "p1");

3.In _layout.cshtml, inject IHttpContextAccessor implementation and use it to get the HttpContext and Session object from that.

@using Microsoft.AspNetCore.Http
@inject IHttpContextAccessor HttpContextAccessor
...
@HttpContextAccessor.HttpContext.Session.GetString("Photo")

result:
