Potential issue: The expression `(image_url_val or "")` does not properly handle all
types. If `image_url_val` is a truthy value that is not a string or a dictionary (e.g.,
a list or an integer), the expression will return the original object. Subsequently,
`DATA_URL_BASE64_REGEX.match()` is called with this non-string object, which raises a
`TypeError: expected string or bytes-like object`. While this requires malformed input,
the function does not perform type validation, making it vulnerable to data from
user-constructed messages or buggy integrations.
