                                    string valueField8 = item[fieldID8].ToString();
                                    SPFieldUserValueCollection userField8 = (SPFieldUserValueCollection)item.Fields[fieldID8].GetFieldValue(valueField8);


                                    DataTable dt = new DataTable();
                                    dt.Columns.Add("ImageUrl", Type.GetType("System.String"));

                                    dt.Columns.Add("NavigateUrl", Type.GetType("System.String"));

                                    foreach (SPFieldUserValue value in userField8)
                                    {

                                        SPUser spuserField = SPContext.Current.Web.EnsureUser(value.User.ToString());

                                        SPList userInformationList8 = SPContext.Current.Web.SiteUserInfoList;

Below is your answer

Guid fieldID8 = item.Fields.GetFieldByInternalName("MyField").Id;
string valueField8 = item[fieldID8].ToString();
SPFieldUserValueCollection userField8 = (SPFieldUserValueCollection)item.Fields[fieldID8].GetFieldValue(valueField8);
DataTable dt = new DataTable();
dt.Columns.Add("ImageUrl", Type.GetType("System.String"));
dt.Columns.Add("LoginName", Type.GetType("System.String"));
dt.Columns.Add("NavigateUrl", Type.GetType("System.String"));

foreach (SPFieldUserValue value in userField8)
{

if(value.User != null) // Value is User
{
    SPUser spuserField = SPContext.Current.Web.EnsureUser(value.User.ToString());
    SPList userInformationList8 = SPContext.Current.Web.SiteUserInfoList;
    SPListItem userItem8 = userInformationList8.Items.GetItemById(spuserField.ID);
    SPServiceContext contextSp = SPServiceContext.GetContext(siteCollection);
    UserProfileManager profileManager8 = new UserProfileManager(contextSp);
    if (profileManager8.UserExists(spuserField.LoginName))
    {
        DataRow row = dt.NewRow();
        var profile8 = profileManager8.GetUserProfile(spuserField.LoginName);    
        string personUrl8 = profile8.PersonalSite.Url;
        string userNames = userItem8["Title"].ToString();
        string pictureURL = userItem8["Picture"].ToString();
        row["ImageUrl"] = pictureURL;
        row["LoginName"] = userNames;
        row["NavigateUrl"] = personUrl8;
        dt.Rows.Add(row);
    }
}
else // Value is Group
{
    SPGroup group = [YourWeb].SiteGroups[user.LookupValue];
    foreach(SPUser spuserField in group.Users)
    {       
        SPList userInformationList8 = SPContext.Current.Web.SiteUserInfoList;
        SPListItem userItem8 = userInformationList8.Items.GetItemById(spuserField.ID);
        SPServiceContext contextSp = SPServiceContext.GetContext(siteCollection);
        UserProfileManager profileManager8 = new UserProfileManager(contextSp);
        if (profileManager8.UserExists(spuserField.LoginName))
        {
            DataRow row = dt.NewRow();
            var profile8 = profileManager8.GetUserProfile(spuserField.LoginName);    
            string personUrl8 = profile8.PersonalSite.Url;
            string userNames = userItem8["Title"].ToString();
            string pictureURL = userItem8["Picture"].ToString();
            row["ImageUrl"] = pictureURL;
            row["LoginName"] = userNames;
            row["NavigateUrl"] = personUrl8;
            dt.Rows.Add(row);
        }
    }   
}
}
RepeaterLinks.DataSource = dt;
RepeaterLinks.DataBind();

Hope it will help to you.
