You are violaing the creative commons license of the original work by not referencing the authors and providing a link to the original. Proper attribution of creative work discourages those who spend time creating. Proper attribution is more than saying you downloaded it. If both the board and chess set are the work of others without doing any significant modification yourself (beyond resizing) - what is the point?
