in adobe stock, according to the licence agreement I can use a licene for one customer but if I want to use the same image for another client I would need to licence that image a second time.
Is it technically possible to licence an image a second time, I can not find any button to licence images twice. Please help.
What I don't understand is that since you are not required to name the client how anyone knows which client it is for or indeed why licencing it a second time makes any noticable difference since no clients are required to be named. The idea that this licence is somehow transfered to the client is also impossibly vague.
You are responsible for keeping track of the licencing needs. There is nothing vague in this concept. Read the licencing terms and it will be completely clear. For each customer, where you use an asset, you really require having a separate licence.
If you use the same licence for a different client, you are indeed violating your licence agreement, and you could be prone to prosecution.
