Extract album art.

[robertapengelly]

Not exactly an issue but how do you extract the album art? I know that it's within the comment header identified by METADATA_BLOCK_PICTURE and that it's base64 encoded, I just don't know how to extract the image after decoding it as it starts with 8 bytes before the mimetype and I don't know how to get to the actual image data.

I tried googling it but I can't find anything (at least nothing that helps) and I've looked at other projects but they don't seem to have an implementation to extract the image.

Thanks for getting in touch.
Off-hand, I don't know what's needed.
I'm busy with other projects and won't investigate right now. However, I'll keep this open for future investigation.
If you find a solution, please let me know or submit a pull request.
