Book covers, Cd covers, posters and logos are all protected by copyrights. The only way to upload them on commons is to get permission from the original author or rights holder. That permission should be send to OTRS. When the receive the permission the will try to verify it and you will get a respond with a ticket number. When you place the ticket number on the image description page it will be fine.
Now I know its kind of hard to get the permission under a free license and most of the time you will not even get permission.
There is a other way, Some Wikis use a Fair use policy, Those project are listed here. On those project you can upload the image locally without any problems, and without copyvio. So please check of your project is listed there, and upload it locally or try to get permission.
