This is a hard question as there is not many details but I will try to answer it the best I can. If it is giving you an error you could possibly be uploading a picture you do not have rights to and it could be getting flagged down.
If you are having problems uploading period then I have had a little bit of issue with this as well. The time it takes for my photos to upload to the picture capsule has sometimes been like 3 minutes. Maybe you are not waiting long enough before closing to actually see and fill in the information associated with the picture.
If neither of these fits you email me and I will try and help.
