Mínimax h3 reference images

Hi! I'm creating videos with Minimax H3, it's really cool, but I'm noticing that I don't see the option to use a reference image (it only shows the intro and outro frames plus the reference voice), and I'm having the prompt generated by LLM. Is there any way to configure this?

My PC:
Os: Windows 11 Pro
GPU: Nvidia RTX 3050 6 GB ( I know, it's not the best)
Ram: 32 GB RAM DDR4
CPU: Ryzen 7 5700G

What have you tried?
