FAQ

How do I view my image's metadata (PNGInfo)?

With the Preview Pane visible, press I in the thumbnail view or with the Preview Pane in focus to show or hide the metadata. You can also click the eye icon at the botton right of the Preview Pane.

What is Rebuild Metadata and when should I use it?

Rebuild Metadata will rescan all your images and update the database with any new or updated metadata found. It doesn't affect your custom tags (rating, favorite, nsfw).

You only need to Rebuild Metadata if a new version of Diffusion Toolkit comes out with support for metadata that exists in your existing images.

Can I move my images to a different folder?

I you want to move your images to a different folder, but still within a Diffusion folder, you should use the right-click > Move command. This allows Diffusion Toolkit to handle the moving of images, and know to keep all the Diffusion Toolkit metadata (Favorites, Rating, NSFW) intact while moving.

If you use Explorer or some other application to move the files, but still under the Diffusion folders, when you Rescan Folders or Rebuild Images Diffusion Toolkit will detect that the images have been removed, then will detect new files added. You will lose any Favorites, Ratings or other Toolkit-specific information.
