Both Vladimir and Guigui answers are prefer way of accessing URL of an image button.

If you also want ID value in addition to URL, you can store multiple values into CommandArgument separated by comma.

<asp:ImageButton runat="server" 
    ImageUrl='<%#Eval("url") %>' 
    OnCommand="Image_Command" 
    CommandName="ImageClick" 
    CommandArgument='<%# Eval("Id")%> + "," + Eval("url") %>' />

protected void Image_Command(object sender, CommandEventArgs e)
{
  if (e.CommandName == "ImageClick")
  {
    string[] commandArgs = e.CommandArgument.ToString()
       .Split(',');
    string id = commandArgs[0];
    string url = commandArgs[1];
  }
}

Cast sender to ImageButton and read its ImageUrl property.

Also, is there a reason you are using command instead of handling ImageButtons click event?
