I said: "created with "JWildfire" by ~thargor6 (details & download -> [link])"
This means my fractal (own creation) was made with a program called "JWildfire" by ~thargor6 (he's the author of the program) and I added a link to his homepage for further information. It's the same as if you write "created with Photoshop or MicrosoftExcel or Nikon Camera or others". The program is a tool for artists.
I add this information to every fractal I submit because people should know which program makes such images possible. Other fractal artists add "created with apo or mandelbulb3D or ultra fractal or others" because they work with these programs.
