I just noticed in the openlp manual I have done up for users that I have used the button images from the openlp source code.
Yes I had include a very short note that I did need to check on license of these images. The openlp work as a total is GPL my question is directly about resources/images and there user ability in documentation.
Of course I can make the documentation legally clear by taking screen shots and cutting the buttons out but this is a lot of effort if its not really required. So far our operational manual has been restricted to internal usage and most likely will stay that way since it contains location exact things.
I have no problems giving openlp project/authors credit for the images and giving up rights to alter them in any other form than size and rights and not to use them about any other program in documentation. I just don't want to have to include like GPL copying to manual if possible as this is add 7 pages to document. Thinking the document is 14 pages long. 1/3 large for licensing declare is why I would forced to screen shot cut and replace. Basically I need a notice that fits in under half a page or I have to replace the images.
