Just upload the screenshots to any image hosting service (I recommend using https://www.talkimg.com/) then post the links here.

Regarding your issue with HeyBets (never heard of it before, tbh), their transfer offer seems too good to be true.
There are many complaints against them on trustpilot and casino.guru from users who got banned after hitting big wins, just like you.
What' s really concerning is how they got your contact information and how they knew your Stake's VIP status?
