   When I called data_uri on the file, it returns this:

   "data:image/jpeg;base64,IzxNb25nb2lkOjpHcmlkRnM6OkZzOjpGaWxlOjB4MDAwMDAwMDJlMzFlMTA+"

   When I tried it on the browser, no image came out. Do you know what caused it or how I could fix it?

   Thank you very much!

   The bug is reproduced and addressed by #87: Base64 must encode stored file data, not the model description. The fix includes binary round-trip and data URI regressions. Keeping this issue open until the PR merges.

   Fixed by #87, now merged. Base64 and data URIs encode the stored bytes rather than the model description. #89 additionally strengthens the binary regression to assert that the upload truly spans multiple chunks.
