• This cache location is not stable across the attachment upload. A newly imported inline image is copied while resource is null, so it is stored at the cache root; after upload, backupLocalData keeps the same localUuid but the remote attachment gains a resource, causing this method to look in a different subdirectory. Reopening the draft offline therefore cannot find the local inline image and renders a blank CID resource. Since localUuid already makes the filename unique, use a resource-independent cache directory.

    val cacheFolder = LocalStorageUtils.getAttachmentsCacheDir(context, extractPathFromResource(), userId, mailboxId)

• Setting an empty alt marks every user-inserted photo as decorative, so screen readers omit potentially meaningful message content. Pass an accessible label into this function (at minimum the attachment filename, until editable alt text is supported) and assign it here instead of always using an empty string.

        img.alt = "";
