Copy ListItems between Identical Lists in same SharePoint site with a ContentType available in it

Hi,

I have a custom List "Product Images" and want to move some of the records in this List to another identical list.

"Product Images" has contenttype "Picture" available in it.

I am using following code snippet available on web:

 public static void CopyItem(SPListItem sourceItem, SPFile file, string destinationListName)
        {
            //copy sourceItem to destinationList
            SPList destinationList = sourceItem.Web.Lists[destinationListName];
            try
            {
                SPListItem targetItem = destinationList.Items.Add();
                foreach (SPField f in sourceItem.Fields)
                {
                    //!f.ReadOnlyField && 
                    if (!f.ReadOnlyField && f.InternalName != "Attachments")
                    {
                        targetItem[f.InternalName] = sourceItem[f.InternalName];
                    }
                                    }
                ////copy attachments
                /* foreach (string fileName in sourceItem.Attachments)
                 {
                     SPFile file = sourceItem.ParentList.ParentWeb.GetFile(sourceItem.Attachments.UrlPrefix + fileName);
                     byte[] imageData = file.OpenBinary();
                     targetItem.Attachments.Add(fileName, imageData);
                 }*/
                targetItem.Update();
                destinationList.Update();
            }
catch (Exception ex)
            {
                string msg = ex.Message;
            }
            // return targetItem;
        } 

Thanks,
