Hey Pickful community,

Following last week’s MCP fix for markdown tables, here’s the next piece: the create_post tool can now attach images.

Ask the AI to publish an article — pass an image and it becomes the cover. Ask it to publish a short post — the image gets embedded inline. Three ways to hand over the image:

• image_url: a remote URL (http(s) or data: URI)
• image_base64: raw base64 bytes
• image_path: a local file path (handy when the AI assistant is running on your own machine)

PNG, JPEG, and WEBP are supported, up to 5MB per image. MIME type is optional — we sniff it from the file header. Remote fetches are SSRF-hardened: private, loopback, and cloud-metadata addresses are rejected, and we follow at most 3 redirects.

This is live on Web, iOS, and Android — no app update needed.

Before this, the only way to “illustrate” an AI-written post was to have the AI describe an image that wasn’t there. Now you can hand it a URL, a path, or raw bytes — the image actually lands in the post.
