对，这也是一个问题，你曾经谈过这个问题。

我个人建议，使用免费可用的图片，比如本文图片来自pixabay.com, 它是明确说了可以用于商用的：

Can I use your images?

You can copy, modify, distribute, and use the images, even for commercial purposes, all without asking for permission or giving credits to the artist. However, depicted content may still be protected by trademarks, publicity or privacy rights. Read more in our blog.

好多中文Steemit用户不懂这细节，直接写：图片来自网络，这是一个没有任何意义的版权声明，在法律上是无效的。
