I asked Servo City if I could use some of their images in my book, and here’s the email they sent:
__________
Yes, you are welcome to use the images…and thanks for asking.
Please send us a copy when completed, we would love to see it and we could help promote it as well on our site.
__________

Excellent! Of course I’ll be sending them a complimentary copy, and I love the unsolicited offer to promote it. This is going to be great.
