I'm in the process of making a skin that I'll be releasing to the public for free...

Must this skin have different images from the IPB default skin? Or can some images be the same...? EG - Can the default themes images be used in a completely new skin and be released?

Also, does the same apply if I was to sell a skin down the road?

Just wanted to be sure.

As you are looking for an official answer I will move your topic into the IPS Feedback forum for you. :)

You can reuse the default images in your custom skin.
