Research direction

Start by reviewing the Web Share API's file-sharing options and the File API issue context. Done means reaching a clear decision on whether shared images should carry an accessible text alternative and recording the resulting specification direction.

Description

TPAC2025

Web Share API images have optional title, but seem to be missing alt.

shareButton.addEventListener("click", async () => {
  const file = new File(data, "some.png", { type: "image/png" });
  try {
    await navigator.share({
      title: "Example File",
      files: [file],
      alt: "Marcos??? 🧐"  // accessible text alternative for the image, equivalent to HTML alt attr
    });
  } catch (err) {
    console.error("Share failed:", err.message);
  }
});
