upload-image_skill

Overview

This skill uploads local or remote images to cloud storage and returns a publicly accessible URL. It supports Base64 uploads and direct URL transfer, detects MIME type automatically, and serves files via CDN. Use it to produce stable, long-lived image links for AI models or web use.

How this skill works

You can provide image data as Base64 or supply a source image URL; the skill uploads the image into the fal-task storage bucket and returns a CDN URL and metadata. File names and folder can be customized; otherwise the service generates a path like {folder}/{YYYYMMDD}/{uuid}.{ext}. The service auto-detects content type and enforces suggested size limits.

When to use it

• Convert a local image file into a stable public URL
• Store a remote image on your own cloud storage to avoid broken links
• Prepare images for AI model inputs (image-to-video, image editing)
• Share images with external services requiring a public CDN URL
• Back up images from client devices or apps to centralized storage

Best practices

• Prefer Base64 upload for local files and URL transfer for remote files to simplify flow
• Keep individual images under 10 MB to ensure reliable uploads
• Provide file_name and folder when you need predictable paths or naming
• Rely on CDN URL returned for production use; it’s optimized for delivery
• Strip no prefixes from Base64 — the skill handles data:image/...;base64, automatically

Example use cases

• Upload a photographed product image and return a CDN URL for an e-commerce listing
• Transfer a remote avatar URL into owned storage to avoid hotlinking and link rot
• Upload source frames for an image-to-video model, then submit the returned URL to the model
• Store user-submitted images for later editing workflows with image-editing AI
• Batch-migrate public image collections into the fal-task bucket for archiving
