    Gumroad Image Uploader

    by JustHandled Labs

    Bulk-update cover images and thumbnails across your Gumroad catalog from a CSV or a folder of files named by permalink. Pre-flight checks validate each image (format, size, corruption) before it hits the Gumroad API, and you get an audit log of every success and failure. No clicking through the dashboard product by product.

    About This Skill

    What it does

    The Gumroad Image Uploader automates the tedious process of updating product cover images and thumbnails across your Gumroad catalog. Instead of manually clicking through the web dashboard for every item, this skill enables bulk updates via a simple CSV manifest or a structured image folder.

    Why use this skill

    Manual uploads are prone to error and incredibly time-consuming for large catalogs. This developer-focused tool provides a robust automation layer that includes pre-flight checks to ensure your assets meet Gumroad's requirements before hitting the API. It handles token validation, file integrity checks, and size warnings automatically.

    Unlike basic prompting, this skill provides logic for mapping local files to remote products using custom permalinks, handles multipart form-data requirements, and manages API rate limits or missing product scenarios gracefully.

    Supported tools

    • Gumroad API v2 integration
    • Python-based execution environment
    • Pillow for image validation and corruption detection
    • CSV and local filesystem processing
    • Support for JPG, PNG, and WebP formats

    Use Cases

    • Apply new branding across hundreds of Gumroad products simultaneously
    • Map local image folders to products using custom permalinks automatically
    • Validate image integrity and file size before attempting API uploads
    • Generate detailed audit logs of successful and failed cover updates

    Gumroad Image Uploader needs terminal access to run the batch upload script. Network access calls the Gumroad API to update product cover images. File read access reads image files from the specified folder. Environment variables read the Gumroad access token from .env. No write, browser, or other network access required.
