A client has recently asked me for the working files of a doucment I put together for them containing several free Adobe Stock images. How can I legally give them the document with the links to the images? Does this breach licensing terms?
If what you are selling the customer is the final document that incorporates Adobe Stock assets, you are not breaching the license terms. Why would the client need to have links to the images?
They want the working InDesign document which when I package would include the image links.
When you included free assets, it will be easy, the client needs to licence the same free assets. Then they are working with their own licence.
An alternative is to let them sign a licence agreement where the explicitly accept to be bound by the Adobe licencing terms.
A last possibility is, that you package and replace the assets with watermarked files or dummy files.
