I'm really new to this industry. I've been asked to create some posters to be used in a television commercial (dummy Lotto posters, to be exact).
1. Can I use stock images (e.g. Lotto balls) and put my own headings and text on top? I have an annual Adobe Stock subscription.
2. Do I need to acknowledge the work?
Sorry if this seems like a silly question - thanks for your help!
