Using a free Stock Image with Standard License for a Bot

I recommend reading the licensing terms. If you have difficulties to understand what can or cannot be done with the specific licence, you need to consult a lawyer specialized in that matter. It is really difficult to give advice like this on a remote situation, where I do not fully understand what you are doing.

(Disclaimer: As always with licensing, this is my interpretation of the rules. I think they are correct and advice is based on reading and interpreting the licence terms and on fair use for both the buyer and the artist/stock company, but I cannot rule out that my interpretation is wrong. I'm not an Adobe employee).
