Shared developer-curated background repository. Theme Studio will pull these as selectable backgrounds for all couples.
Use the bulk uploader to add real image files. This page writes the correct image URLs into the shared background library index automatically.
Do not import legacy-theme-backgrounds.json directly. That file is only a reference list of older remote backgrounds. If you still want any of those, download the actual image files you like first, then upload the files here.
If you want a JSON backup, use Download Library JSON after uploading. That exported JSON is the clean current library index with the new stored image URLs.
Use the main background file chooser on the left for both single and bulk upload. It now supports selecting multiple image files at once.
For bulk upload, choose a category, leave Background Title blank, then select multiple files and click Upload to Shared Library. Each file will use its filename as the starting title.
