Picture Block

This block is for storing pictures associated with the file, most commonly cover art from CDs. There may be more than one PICTURE block in a file. The picture format is similar to the APIC frame in ID3v2. The PICTURE block has a type, MIME type, and UTF-8 description like ID3v2, and supports external linking via URL (though this is discouraged). The differences are that there is no uniqueness constraint on the description field, and the MIME type is mandatory. The FLAC PICTURE block also includes the resolution, color depth, and palette size so that the client can search for a suitable picture without having to scan them all
Format: Info <32> The picture type according to the ID3v2 APIC frame: (There may only be one each of picture type 1 and 2 in a file) <32> The length of the MIME type string in bytes. The MIME type string, in printable ASCII characters 0x20-0x7e. The MIME type may also be --> to signify that the data part is a URL of the picture instead of the picture data itself. <32> The length of the description string in bytes. The description of the picture, in UTF-8. <32> The width of the picture in pixels. <32> The height of the picture in pixels. <32> The color depth of the picture in bits-per-pixel. <32> For indexed-color pictures (e.g. GIF), the number of colors used, or 0 for non-indexed pictures. <32> The length of the picture data in bytes. The binary picture data.
