It depends on what kind of visibility you mean. If your goal is to rank in Google Images, adding relevant images can help you show up under the Images tab, especially if the page already performs well and the images are optimized properly. In that case, pictures can create an additional path for traffic.
But if you mean traditional rankings in the main search results, adding more pictures by itself usually will not increase your SEO rankings. If it did, low quality pages could slap on a few images and expect an instant boost. Images do not equal authority or expertise over a topic, and they do not replace the fundamentals that Google rewards.
Images can still be useful for user experience, explaining concepts, and increasing engagement, and that can support a strong page. Still, do not add pictures expecting to jump to page one. Like most SEO, outcomes depend on the keyword and your industry. If you want real ranking gains, focus on topical authority, content quality, and earning backlinks.
