It might not have been your intention, but by not crediting your sources, you are putting across the impression that you are stealing - and your disclaimer is not sufficient to ease this situation. Each artist has put time and effort in their piece and should be credited accordingly.

I see that the comment that had been posted already about this issue has been either deleted or screened. Sadly, this is not helping to ease the impression you are giving.

Please take the time to credit your sources.
