Study showing it’s better to have images in their own row on a text/news article page, rather than in a column with text wrapping around it

I'm remembering a usability study I once saw that demonstrated it's better for scanning or readability on a website's news article or text-heavy page to have any photos as their own row by themselves, rather than pinched into a column with text wrapping around it.

Text wrapping around the image was kind of a legacy pattern from print magazine design.

Like this:

Like how most major news publishers do it.

But now I can't find the study that showed that.

Does anyone have any studies that describe what I'm talking about? I don't want to justify by merely saying "that's how NYTimes does it".
