< Picture's color depth in bits-per-pixel.
< Length of binary picture data in bytes.
< For indexed palettes (like GIF), picture's number of colors (the number of palette entries), or \c 0 for non-indexed (i.e. 2^depth).
< Picture's height in pixels.
< Picture data's MIME type, in ASCII printable characters 0x20-0x7e, NUL terminated. For best compatibility with players, use picture data of MIME type \c image/jpeg or \c image/png. A MIME type of '-->' is also allowed, in which case the picture data should be a complete URL. In file storage, the MIME type is stored as a 32-bit length followed by the ASCII string with no NUL terminator, but is converted to a plain C string in this structure for convenience.
< Picture's width in pixels.
< The kind of picture stored.
< Picture's description in UTF-8, NUL terminated. In file storage, the description is stored as a 32-bit length followed by the UTF-8 string with no NUL terminator, but is converted to a plain C string in this structure for convenience.
