Newbie Question Re: image uploading

[dita]

I`ve looked through this document https://docs.google.com/document/d/1wB80CH3zecXccfQ4Et8NxYa-G1bQuo7eo1YHvkYQ728/edit but I still a bit unsure on the stance regarding what sources of images are allowed.  I`ve uploaded some, which have got accepted, but should the images be completely my original creation.  E.g.  A box cover which I have personally scanned, or can I be a high quality image from a 3rd party website, obviously, as point 10(a) states, with no watermarks.  I think its point 11a "Must be scanned, created or customised by a user" which has may concerned.

Thanks for any clarity anyone can provide.
