I work in aspnet core mvc technology, I manage to add an image, it does go to wwwroot, but the image does not display well in the browser Example: enter image description here

enter image description here

My Controller:

 [HttpPost,ActionName("CreateAnimal")]
    [ValidateAntiForgeryToken]
    public async Task<IActionResult> CreateAnimal([FromForm] CreateAnimalViewModel model)
    {
        string wwwPath = _Environment.WebRootPath;
        string contentPath = _Environment.ContentRootPath;
        ModelState.Clear();
        model.Animal!.Category = _context.Categories.Where(c => c.CategoryId == model.Animal.CategoryId).FirstOrDefault()!;
        var path = Path.Combine(wwwPath, "Images", model.Photo!.FileName);
        if (model.Photo.Length > 0)
        {
            using var stream = new FileStream(path, FileMode.Create);
            await model.Photo.CopyToAsync(stream);
        }

        model.Animal.PhotoUrl = path;
        _context.Add(model.Animal);
        
        if (TryValidateModel(model))
        {

            _context.Add(model.Animal!);
            await _context.SaveChangesAsync();
            return RedirectToAction(nameof(Manager));
        }

        ViewBag.CategoryId = new SelectList(_context.Categories, "CategoryId", "Name");
        return View();
    }

My View:

@model IEnumerable<PetShop.Data.Models.Animal>
<table id="Table">
<thead>
    <tr>
        <th>@Html.DisplayNameFor(model => model.PhotoUrl)</th>
        <th>@Html.DisplayNameFor(model => model.Name)</th>
        <th>@Html.DisplayNameFor(model => model.BirthDate)</th>
        <th>@Html.DisplayNameFor(model => model.Description)</th>
        <th>@Html.DisplayNameFor(model => model.Category.Name)</th>
        <th>@Html.DisplayNameFor(model => model.Category)</th>
        <th>Edit Animel</th>
        <th>Delete Animel</th>

@foreach (var item in Model!) {

           <img class="Images" src="~/Images/@Html.DisplayFor(modelItem => item.PhotoUrl)">
       </td>
       <td>@Html.DisplayFor(modelItem => item.Name)</td>
       <td>@Html.DisplayFor(modelItem => item.BirthDate)</td>
       <td>@Html.DisplayFor(modelItem => item.Description)</td>
       <td>@Html.DisplayFor(modelItem => item.Category.Name)</td>
       <td>@Html.DisplayFor(modelItem => item.CategoryId)</td>
     
           <a asp-action="EditAnimel" asp-route-id="@item.AnimalId">
           <input type="submit" value="Edit">
           </a>
   
           <a asp-action="DeleteAnimel" asp-route-id="@item.AnimalId">
           <input type="submit" value="Delete">
           </a>
