It would require Liquid knowledge to implement this feature, I'm afraid that unfortunately there is no simple copy-paste solution otherwise I'd happily guide you through.
If it is of your wish, I present myself available to help you. You'd have this exact "text/image" section available in every page. We could also include a button to show/hide it.
I work full time as a developer and have worked with dozens of people in this very forum. Precisely 26 of them were kind enough to write recommendations about my work.
You can read their reviews (written from their original Facebook accounts for legitimacy purposes) clicking here.
here is solution for you.
The first you need follow this path:
Themes => edit code => sections:
Click on Add a new template, example "new_section_name"
next step you need to open the file featured-row.liquid in the sections folder(this is the section Image with Text file), copy all code and paste into your new section.
Next step you need open the file product.liquid in folder Templates and add this code
like this image:
and the last: Open the product page in customize and add your content.
