Different images, the same family
One illustration looks like a photograph, another like a poster, the third like an icon. Each might work on its own, but they clash in a post listing. For a series, we suggest first agreeing on a palette, background and way of depicting objects. Then change the subject while keeping those reference points.
You can use Nano Banana 2 Lite for this exercise. Google announced it on June 30, 2026, as a fast, economical image model in the Nano Banana family. The announcement lists Google AI Studio, Gemini API and Gemini Enterprise Agent Platform as access points for app developers. Speed and economy are the manufacturer’s claims here.
Write down what should stay the same
A style card needs only a few decisions about proportions, color, background and form. For example: “landscape illustration, warm light background, dark outline, one orange accent, simple flat shapes, plenty of empty space, no text.” Keep that part in the description of each image.
As for subjects, we suggest papers connected by colored thread for research, a small film set for video, and three workstations passing a box between them for automation. An illustration should hint at the topic, so be careful not to imply a feature the article never discusses.
Put them side by side to see whether they form a series
Shrink the images to blog-card size and place them together. Can you still recognize the main objects? Is one graphic drowning out the others while another becomes an unreadable blob? This view makes it easier to decide what to simplify and where to leave more room.
If the idea works but the composition is crowded, reduce the number of elements. Leave the rest of the description alone so you can see what that one change achieved. Store the style card and brief notes with the files. You will not have to reconstruct the whole idea from memory for the next post.
See what happens on a phone too
An image file and its cropped version on a page can look different. Before publishing, check the crop in a narrow viewport. The main element should stay in view, while the title still attracts attention. In a dense list of posts, a quieter illustration can work better with the text.
Keep information essential to understanding the article in ordinary text too. Alt text, read by screen readers among other tools, should convey the image’s meaningful content. For a purely decorative image, it can remain empty. The series keeps its character, and the posts still make sense without illustrations.
