Cover Artist: AI Image Generator for WordPress Posts

Cover Artist is a free WordPress plugin that helps you generate AI cover images and inline images from inside the post editor. It can read the relevant context from your article, suggest a visual brief, generate an image with a provider you configure, then save the result to your WordPress media library with a useful filename and alt text.

I built it because the supposedly simple task of adding a good blog image had become annoyingly multi-step: make an image, download it, crop it, compress it, name it properly, upload it, and then write alt text. This keeps the workflow in WordPress, while still leaving the editorial decision with you.

What Cover Artist does

• Generates AI-powered cover art from your post title and content.
• Creates inline images from the context around a heading or selected block.
• Lets you use the suggested visual brief or write your own image prompt.
• Works from the media library as well as the block editor, including a quick inline-image workflow.
• Saves accepted images to the normal WordPress media library, ready to reuse.
• Creates SEO-friendly image filenames and alt text as part of the workflow.
• Offers OpenAI and Google Gemini options, using API keys you provide.

How the AI image workflow works

When you ask for a cover image, Cover Artist uses the post’s context to propose what the image should communicate. You can edit that suggestion before generating anything. For an inline image, it concentrates on the nearby section rather than treating every image as a generic representation of the whole article.

That matters when a post changes subject part-way through. An article may need a restrained feature image at the top and a more literal visual to explain one specific section. Cover Artist is designed to handle both without forcing you out to a separate image tool.

Install the AI image generator for WordPress

1. Install and activate Cover Artist from the WordPress plugin directory.
2. Open Cover Artist in the WordPress admin menu.
3. Add at least one supported image-provider API key—currently OpenAI or Google Gemini—and save your preferences.
4. Open a post, then use the Cover Artist controls in the media library or the quick inline-image tools in the block editor.

You pay the AI provider directly for the requests you make. That keeps the plugin free and gives you control over the account, models, image dimensions, quality, and provider settings you use.

Create a cover image or inline image

1. Open the post you are writing or editing.
2. For a cover image, open the media library and choose the Cover Artist tab. For an inline visual, use the Cover Artist control in the relevant block workflow.
3. Review the proposed prompt. Change it if the image needs a different subject, composition, style, or aspect ratio.
4. Choose your provider and image settings, then generate.
5. Review the result. Generate another option if it is not good enough; otherwise insert it or use it as the featured image.
6. Check the generated filename and alt text before publishing, especially where exact facts, accessibility, or brand language matter.

Privacy, permissions, and editorial responsibility

Cover Artist contacts an AI provider only after you configure an API key and actively ask it to analyse content or generate an image. Depending on the feature, the relevant post title, article excerpt or context, prompt, and image settings are sent to the provider you select. Read the provider’s terms and privacy policy before use, and do not send sensitive or confidential material you are not entitled to share.

Generated images remain editorial work. Check that the output is appropriate, accurate, and safe to use for your audience. Your rights and permitted uses are governed by the terms of the selected provider and any other rights that apply to your content; the plugin does not make a blanket ownership guarantee.

Is it useful for SEO?

Images do not substitute for useful written content, but a clean media workflow helps. Cover Artist can give the file a descriptive name and propose alt text, which is much better than a camera-roll filename. The important step is still human review: alt text should describe the image in context, not awkwardly repeat a keyword.
