While creating our own art is most often preferred, sometimes the better choice is to modify someone else’s art.
Proceed along three guidelines:
#1. Begin with Creative Commons image search, but don’t assume that just because the image showed up on a Creative Commons search that it’s really free to use. We all know how easy it is to upload or share pictures online. That movie poster for the blockbuster that came out a week ago? Not likely Creative Commons already.
#2. Taking someone else’s work and cropping it or removing part of the background is an insufficient modification.

This is modification:
Can you count at least three modifications made to the original image?
#3. In any case, make sure you give credit to the original artist or owner of the creative work.
