Printable Asset Library
Browse the categorized line-art images you generate and upload to R2. This page reads the R2 listing API, displays each asset as a printable card, and prepares the page to send uploaded assets into the generator.
Loading assets
The page is checking the R2 asset library API.
How this page works
R2 is the source
Generated assets are uploaded to R2. This page fetches a JSON list and renders the images as searchable printable cards.
Metadata matters
Use custom metadata
Add category, subject, title, style, age, difficulty, and tags as R2 custom metadata so the page can filter and label each card.
Next step
Replace generator choices
The generator can read the selected asset URL from this page and use it directly in the printable worksheet.
Ready for the new workflow?
Generate images, upload to R2, display them here
