Base64 - Exif metadata

Is it possible to add EXIF metadata for "ImageDescription" to a base64 JPG image string? Could this one have a EXIF data "ImageDescription" that claims it's the Stack Overflow logo? http://pastebin.com/0v开发者_StackOverflow社区UsybJQ

Thanks.

You could add EXIF metadata by reading the text format jpg image, adding the metadata to the image in memory, then saving it again in the base 64 text format.
