pw-image-generation_skill

Overview

This skill implements an end-to-end AI image generation and processing workflow focused on cost control and consistent style. It supports text-to-image, image-to-image, batch generation with per-image confirmation, image hosting management, long-image merging, and PPT packaging. The core idea is: analyze style → design prompts → confirm each generation → save outputs to avoid wasted API usage.

How this skill works

The tool reads prompt files from a local prompts/ folder, shows each prompt for user confirmation (yes/skip/quit), then calls the configured image generation API and saves results to an images/ directory. It can upload reference images to an image host and store deletion links, analyze visual style from a URL or local file to produce prompt suggestions, and post-process outputs by merging images vertically or packaging them into a PPTX. Scripts run with Bun/Node and use a simple config/secrets file or environment variables for API keys.

When to use it

• You need to generate illustrations, article images, or social media visuals from text prompts.
• You have a reference image and want new images in a similar style (image-to-image).
• You want to batch-generate a series of style-consistent images but avoid blind bulk consumption of API credits.
• You need to merge multiple images into a long vertical image for social posts or tutorials.
• You want to package generated images into a PPT for sharing or presentations.

Best practices

• Keep prompts clear and consistent: use a single language and include style, subject, scene, atmosphere, and technical details.
• Generate 1–2 test images first, adjust prompts, then batch-generate remaining items.
• Use the per-image confirmation to skip low-value prompts and avoid unnecessary API calls.
• Name prompt files with numeric prefixes (01-, 02-) so outputs sort predictably.
• Upload high-quality reference images (>=1024×1024) when doing image-to-image and include explicit constraints in the prompt.

Example use cases

• Create article illustrations: prepare prompts per section, confirm each generation, and export final images to images/ for publishing.
• Produce a slide deck: generate images for each slide, then run the PPT packaging script to create a 16:9 PPTX with one image per page.
• Make a long-form social post: generate or collect images, then merge them vertically into a single long image for platforms like WeChat or Instagram guides.
• Style transfer workflow: upload a reference image to the image host, use the returned URL in prompts, and generate multiple variations that preserve color and composition.
