We are currently developing a commercial application. We found some images(icons) which are under GNU/GPL license.
I'm not an expert in this kind of things, but I was wondering if it is legal to use the image inside our commercial application(which is definitely not under GNU/GPL license).
For what I read here, some obligation are induced when we modify the file. But in our case, we use it in a bigger application.
- Is it legal to use it?
- Is there something we should absolutely do?(Like indication in the license of our application that some parts are under GPL/GNU? Or indicate where this icon is coming from?)
