I am just about to release a few software projects under the Apache Open Source License 2.0.
While creating the projects I have purchased the legal rights to royalty-free images which I use in the project. A specific example is the image I use as an icon.
However, the original license doesn't allow others to use those images (for derivative products) as they like, since the future users haven't paid the royalty.
Am I allowed to include the royalty-free images along with the Open Source project on GitHub (for example)?
Is there a proper way to indicate that certain resources (images, sound files, etc) are not included in the Open Source code itself?
I know many of these answers may require exact detailed information. I'm just attempting to get a general idea.
