It may not be the best way, but you can check if a file exists using something like this:

@{
    var filePath = GetString("Item.ImagePath"); // e.g., /Files/Images/hest.png
    var absolutePath = System.Web.HttpContext.Current.Server.MapPath("~/" + filePath);

    <pre>@filePath
@absolutePath
@System.IO.File.Exists(absolutePath)
</pre>

    if (System.IO.File.Exists(absolutePath))
    {
        // …
    }
}

Best regards,
Mikkel

Thanks Mikkel

So if the file im looking for is at this path: "/Files/Images/ProductImages/@GetString("Ecom:Product.Number")-1_600.jpg" how would that variable look like? If I insert into your filepath I get the error:

Line 20: Invalid expression term '/'
Line 20: ; expected
Line 20: ; expected

I guess I need to escape the path somehow?

Try

var filePath = "/Files/Images/ProductImages/"+GetString("Ecom:Product.Number")+"-1_600.jpg";

or

var filePath = string.Format("/Files/Images/ProductImages/{0}-1_600.jpg", GetString("Ecom:Product.Number"));
