Using Wikipedia images in iBook Author?

Question

Can anyone please tell me more about the problems associated with using GENERIC and SHARE ALIKE images.  Some images seem to have both.
An earlier thread indicated that using SHARE ALIKE will mean all images in the IBook will make them SHARE ALIKE too!

Answer 1

The feedback from Wikipedia indicates that the information about Wikipedia images affecting the copyright of the images of an author in an iBook is totally false!!!!!!!
I enclose their return message:-
You didn't post a link to the particular license that controls distribution of the image in question, so it's difficult to comment. However, a more general comment…
Did you get this response from a Wikipedia executive, or is it just a reply to a question on a talk page? If the latter, all it is is a comment from any one of a hundreds of thousands of Wikipedia contributors, meaning that it might not be correct.
I have myself uploaded a number of images to Wikipedia. (Of course, I had copyright on those.) Some of these images I placed into the public domain. If you want to use one of those images, go ahead. They are free to use, and you don't even have to acknowledge a source.
Other images I published are under the Attribution-ShareAlike 3.0 Unported license. That license states that, if you want to use my image, you must acknowledge me as a source and you must make your work available under the same license:
Attribution-ShareAlike
CC BY-SA
This license lets others remix, tweak, and build upon your work even for commercial purposes, as long as they credit you and license their new creations under the identical terms. This license is often compared to “copyleft” free and open source software licenses.
If a book contains a mixture of copyrighted images and Attribution-ShareAlike images, I expect that the book cannot be published under an Attribution-ShareAlike license because it's not possible to simply give away the copyright to a copyrighted image: one license requries you to allow others to freely re-use your book, whereas, for the copyrighted images in your book, you presumably have permission to use those images specifically in your book only, so the two licenses are in conflict.
The ShareAlike license makes some exceptions for works that are deemed "collections." However, my reading suggests that, if you include an Attribution-ShareAlike licensed image in a book, that does not make the book a "collection."
Also note that, if you include an Attribution-ShareAlike licensed image in a book, it looks like you cannot sell that book with DRM:
When You Distribute or Publicly Perform the Work, You may not impose any effective technological measures on the Work that restrict the ability of a recipient of the Work from You to exercise the rights granted to that recipient under the terms of the License.
The DRM interferes with the free re-use of the work, and so violates the ShareAlike license.
Licenses such as ShareAlike have their roots in the eighties, with the Copyleft licensing. The idea of copyleft is to say "We give you something to use. You can use it to create your own stuff, but only if you make what you create available for others too."
Now, please, take all of the above with a grain of salt. I'm not a legal expert. If you have any doubt about the consequences of including an image in your book, I strongly recommend that you consult a copyright expert, particularly if your book includes images that use different licenses.
