Check file type and return true if its of gif, jpeg, pjpeg, png, jpg, bmp etc if it is of any other type then return false
 

public static bool CheckValidJPGGIF(ref FileUpload file)
{
    if (file.PostedFile.ContentType.ToLower() == "image/gif" || file.PostedFile.ContentType.ToLower() == "image/jpeg" || file.PostedFile.ContentType.ToLower() == "image/pjpeg" || file.PostedFile.ContentType.ToLower() == "image/x-png" || file.PostedFile.ContentType.ToLower() == "image/jpg" || file.PostedFile.ContentType.ToLower() == "image/bmp")
    {

            return true;

    }
    else
    {   
            return false;
    }
}
