jsontoimg for WordPress 1.0.0

Release notes

First public release of the jsontoimg WordPress plugin. Editors can render named templates as signed images in posts, without exposing an API key on the frontend.

Highlights

• Settings → jsontoimg — save an API key and optional base URL, then Test connection.
• Gutenberg block — pick a template, fill schema-driven layer fields, preview the signed image.
• Set as Featured Image — download the render into the Media Library and assign it as the post thumbnail.
• [jsontoimg] shortcode — same signed <img> for classic content.
• PHP helpers — jsontoimg_sign_url(), jsontoimg_render_image(), jsontoimg_list_templates() for themes.

Signed URLs use POST /api/v1/img/sign. Visitors fetch GET /api/v1/img/{template} with sig; the key never appears in HTML. The first unique GET bills once; later hits are cache hits. Minted URLs are cached in WordPress transients.

Requirements

• WordPress 6.6+
• PHP 7.4+
• API key from Integrations → API keys

Install

Upload jsontoimg.zip via Plugins → Add New → Upload Plugin (not jsontoimg-1.0.0.zip, which nests the folder). Activate, then add the key under Settings → jsontoimg.

Notes

• image_url layers need a public https://… file ending in .png, .jpg, .jpeg, or .webp, or an Assets path /api/uploads/files/{id}. Placeholder CDNs such as placehold.co are often blocked at render time.
• Featured image works in the post/page editor on types that support thumbnails. Save the post first if the button is disabled.
