Extent the photo width to the right side & shrink the text part

In this section, I want to make the photo wider to the right side and to make the text part smaller.

I have tried to change the photo div’s width size, but it stays the same size.

How can I extend the photo part and reduce the text part correctly?

It only changes the width when I replace the photos. Why?
Are your photos exactly 545px so they can’t get bigger?

If you set width 100% on your image, it should work.
If not, please send me website url so I can check

I am talking about your images.
It is by default on 100%
Anyway, I added new images with larger pixels and it got better.
I guess the dimensions needed to be configured before uploading them.
