Urgent WordPress Homepage Image Upload

I have a WordPress site and a single image that is already prepared; I just need it placed on the homepage right away. As soon as I share admin access, please drop the image into the correct section, check that it scales properly on desktop and mobile, clear any cache if required, and let me know once it is live.

Deliverable:
• Image visible on the homepage within 10 minutes of receiving credentials, with a quick confirmation screenshot.

That’s all—speed and accuracy are the priorities here.
