1. You don’t need to convert an image value into a file format separately. Bubble handles that for you.
  2. Make sure the field in your database is set as either “List of Files” or “List of Images” if you’re saving multiple images.
  3. After uploading your desired images to a multi-file uploader, ensure you use a button (or similar trigger) to run a workflow like “Create a New Thing” or “Make Changes to a Thing” to save them to your database.

If you’ve already done all of this and it’s still not working, feel free to share more details, like screenshots or a video of your setup. I’d be happy to help
