Question about Marketing Material

[Wise Gambler]

Hello!
I am pretty new to the affiliate world having started to build a website providing Poker Room reviews and Promotion details as well as Bonus links and Codes.

Until now I am making some good progress but still there is lots of work to do.
I was just wondering if it was ok to use parts of Screenshots to display the different Promotions that Poker Rooms are currently providing.
Do the rooms tolerate using that kind of material? You can for example find a list of the persisting promotions on every poker room page of my site. If that was not allowed I would change the concept.

On the other hand I plan to add multiple Pages regarding Poker Books, Tutorials and Articles, as well as a list of Pros associated with their contracted Online Poker Rooms.

I plan to completely erease the online casino section for seo reasons and maybe launch a second website for casinos once the time has come.

Any feedback appreciated
Have a great day
