The Short Version
- Six steps became one. Making an AI image for a WordPress site meant generating it, downloading it, resizing it, converting it, uploading it and typing the alt text by hand. Claude and I built a free AI image generator WordPress plugin, PostHelp Images, that does all of it inside wp-admin.
- Your site gets lighter, tidier images. Each image is sized, converted to WebP and given alt text before it reaches your media library. That helps pages load and helps people who use screen readers.
- It costs cents, not a subscription. The plugin is free. With your own OpenAI key, you pay OpenAI a few cents an image.
Who Is Making the Pictures for Your Website?
Somebody has to make the images on your site, and an AI image generator WordPress plugin should do that job. Today that usually means an AI tool, a download, a resize, a file conversion, an upload and a line of alt text typed by hand. Six steps, every time. If you've ever wondered why a simple page update takes your web person so long, this loop is part of the answer.
Across my own sites and my clients' sites, it adds up. So I designed one that keeps the whole job inside wp-admin (the WordPress dashboard).
One Plugin, Start to Finish
PostHelp Images is the plugin. I designed it on June 16, 2026, and Claude built version 1 from my spec the next day, to a staging site (a private copy of a site, used for testing). You type an idea. It turns that into an image prompt you can refine in plain language. Then you generate the image.
This AI image generator WordPress plugin went from 1.0 in June to 1.5.0 on October 14, 2026. It replaced the n8n automation I used for posthelp.ai and MeetaNeed, and I make the images on sitezinc.com with it. Here is the PostHelp Images page, and here is where it sits among my other PostHelp tools.
What It Does for Your Site
Images that look like your business. Add a reference photo and the result matches a real truck, storefront or product. No generic stock look.
Lighter files and alt text, done for you. It resizes to your max width, converts to WebP, JPEG or PNG on your own server, and writes the alt text if you leave it blank. Smaller files help pages load. Alt text is what a screen reader reads aloud for someone who can't see the picture. I wrote about why file size matters in Images for a Website: Rightsizing for Performance.
Old images get replaced without breaking links. It can swap an existing image in place and keep its URL. Nothing that points at the old picture goes dead.
A pile of ideas becomes a pile of images. Import a spreadsheet of ideas and generate them as a batch. A link under a post's Featured Image box makes an image for that post and sets it as the featured image. Five starter style templates come built in.
How Claude and I Split the Work
Here is the division of labor. I decided what the plugin does, how it's priced and how it looks. I tested every release on staging before it shipped. Claude wrote the code, ran the deploys and checked them.
What made that split work: a spec complete enough to build from, and a staging site where I test before anything goes live.
What an Image Costs, and What It Doesn't Do Yet
In October I ran three prompts on staging, comparing OpenAI's gpt-image-2 against gpt-image-2.5-flare at medium quality. Flare matched it on quality, exact text included. It cost about 0.91 to 0.93 cents per 1536x864 image, against 3.31 to 3.33 cents. Three prompts is a small test, so take it as a finding, not a law. Flare is now the default.
This AI image generator WordPress plugin is free. You use your own OpenAI key and pay OpenAI directly, usually a few cents an image. Or you connect a free PostHelp account, get 5 free images after confirming your email, then buy packs of 25 for $10. No subscription, no expiry. Your own key is always used first.
It isn't in the WordPress.org plugin directory yet. I submitted it on October 14, 2026, and the product page says it's waiting for review. Until it's listed, you download it from the page above.
If Your Site Needs Images, Let's Talk
If your site needs fresh images and you'd rather not spend an afternoon in that loop, tell me what you have. I'll tell you what I'd do. My WordPress services page shows what else I handle.
If you're technical and want to know how the plugin works, ask me. I'll walk you through it.
Questions I Expect About This
Is PostHelp Images really free?
The plugin costs $0. You pay for the images themselves, either to OpenAI with your own key (usually a few cents each) or through a free PostHelp account, which gives you 5 free images and then sells packs of 25 for $10.
Is it in the WordPress.org plugin directory?
Not yet. I submitted the plugin on October 14, 2026, and the product page says it's waiting for review. Until it's listed, you download it from posthelp.ai.
Will it break images already on my site?
No. It can replace an existing image in place and keep its URL, so pages that use that image keep working.
