Free images for client's roll up

What is your mother tongue?

Let me state the obvious:

Free images come with a standard licence, so anything that fits a standard licence is OK. This also includes commercial projects. You need only to credit Adobe stock and the author if you are using the asset in an editorial way. Standard licences cannot be used for assets that get used on objects for sale: T-shirts, mugs, posters.

Now what are you doing: You want to license Adobe stock assets to be put on a roll-up display for a company or an organization. The roll-ups are not the product for sale. So, this is a great application for stock asset under a standard licence.

You may modify the asset so that it fits your needs. Using the companies logo with the asset or nearby the asset is no problem. It would be utterly limiting, if you would not be able to use an asset this way.

As I always do with licensing questions, I still point to the licensing terms. If there are still questions, please update this. If you want to get a qualified answer from a lawyer, you will need to ask one. I am not, and I don't have a formal training in law.

(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).
