There may be some issues with the upgrade that Shawn is doing as we speak.
You can only upload one picture at a time.
Each time you want to upload a new pic you must select that new pic from the pictures file on your computer, it almost sounds like to me that you are not selecting the proper file name for the new pic and the photo album is re loading the first pic you successfully uploaded.
You cannot upload pics directly from other websites, you must save them in your pics file on your computer first, then upload them.
If the pics you are trying to upload are huge, you may have to downsize them.
