I used my backup and then they were gone. However, if you click the + first and then select what ever from iphoto, the - sign is highlighted which means of course that you can remove a folder or your single selection. I must have got them into the sidebar improperly as my son pointed out. I tried it out so now I know.
So to import all or any pics, you must click the + first and then a window appears giving you your options. Thanks for your time fellows.
