The artwork policy with regard to copyright ownership varied with each company I worked for. Some of them believed that, once their clients paid for and published a creative work, they owned it and could reuse it wherever and whenever they chose to at their discretion. Others believed that any artwork they created for a client belonged to the creator--not the client--and could only be reused with their permission at an additional charge.
I'm speaking about this here because there are so many Internet marketers producing ebooks for their businesses nowadays, and I want to make sure you understand the artwork policies of whomever you're dealing with to produce your book covers and interiors for you. It's a conversation you should always have upfront, and you need to make sure you're reading through your artwork and publishing contracts ahead of time before you ever enter into an agreement with anyone.
Having been on both sides of this coin--being both the service provider and the paying client at various times in the past--it is my opinion that the copyright for a creative belongs to the paying client, and all the high-resolution artwork should be returned to that client upon receipt of payment. I have many reasons for this that I'm happy to elaborate on here if asked.
What are your personal thoughts on it? In your opinion, who owns the artwork? And why? (If there are any graphic designers on this site, I realize this conversation may get a little heated.)
