The attribute max-image-preview:large is a meta tag directive that regulates the display of image previews on web pages, playing an important role in the context of SEO (Search Engine Optimization) and Joomla Structured Data.
This attribute becomes relevant due to the way search engines, like Google, display images in previews when a page is shared or appears in search results.
Here is a more detailed explanation of its importance in SEO:
Control over image display
The max-image-preview directive allows website owners to set the maximum size of images that search engines, such as Google, can use in snippets (the page previews displayed in search results).
There are three value options for this directive: none, standard, and large. The large value allows larger images to be displayed in search results.

"Greater visibility and attractiveness in search results."
When the large value is used, Google may display a larger image in the preview, making your page stand out more in search results. Large images tend to attract more user attention, which can increase the click-through rate (CTR), as eye-catching visual elements generally generate more interest.

Positive impact on the click-through rate (CTR)
Larger images in previews can increase the likelihood of users clicking on your link, especially when compared to results with smaller images or no images at all. An increase in CTR (Click-Through Rate) usually means more traffic to the site, directly contributing to better SEO results.
"Relevance for sharing on social media"
Although the main focus of this directive is SEO, it can also impact how your page is presented when shared on social media, which often use similar metadata to search engines. A larger and more attractive image can generate more engagement and interactions on social platforms.
"Control over visual content"
In certain cases, you may prefer that large images are not displayed in previews, especially if the content is not appropriate or relevant to the first impression you want to make.
However, if the image is visually appealing and aligned with the page content, the large value ensures that it will be displayed in its entirety, maximizing its engagement potential.
