ImageUrls must be to a specific file - which means a specific file name, including extension.

There is no mechanism for saying "one of these three possibilities, if any of them exist" - instead you will have to check for the file existance (File.Exists[^] will do it) to locate teh specific file, and then use the full URL for that.

You can do the following.

C#

if (System.IO.File.Exists("~/Images/" + d.Name+".jpg"))
{
     imgbtn.ImageUrl = "~/Images/" + d.Name+".jpg";
}
else if (System.IO.File.Exists("~/Images/" + d.Name + ".jpeg"))
{
     imgbtn.ImageUrl = "~/Images/" + d.Name + ".jpeg";
}
else if (System.IO.File.Exists("~/Images/" + d.Name + ".png"))
{
     imgbtn.ImageUrl = "~/Images/" + d.Name + ".png";
}
