How to create 2 rows with 25%75% in about section?

Hi there,

I would like to add in ABOUT section small photo on the left side and on the right side text.
It should be like 25% for image and 75% for text.
So not the whole background image.
How can I do that?
It would be only on about page.
The rest of pages are following the Illdy template.
Please explain in details.

Thanks a lot!
