🖼️ Gumroad Image Uploader
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

Creator
JustHandled Labs builds focused agent skills for the work nobody wants to do by hand. Each one is a single repeatable job done well: catching the security and data mistakes that quietly ship, keeping docs and tests honest, gating the commands an agent is about to run, sharpening writing, and handling the founder chores around launches, outreach, and brand setup. Not generic AI productivity. Specific workflows that are easy to run, review, and repeat. Maintained by H.J. Westerfield, with a background in communications, editing, project coordination, customer support, and practical AI systems. Tools for people who want useful automation without theatrical complexity.
