Storing url of a nested image


I have a picture that is nested within an image-wrapper. When inspecting source code, it looks like this:

I have the complete Xpath of the class=‘image’ thing and what I want is to use storeAttribute to get the url of that image (the url property I highlighted in the screenshot)
I tried storeAttribute | //div[1]/div/div[2]/div[1]/div[1]/div@src | img_url
but that did not work. I tried using @href, unsuccessfully too. So, knowing that the Xpath is correct what is the attribute of that url property?
Thank you

This is the CSS url parameter, I think storeAttribute does not work there.

But maybe use sourceExtract with a regular expression?

Thank you very much for tip
