Don't convert album art on music conversion

[Globs]

I've already seen this somewhere but can't find a matching bug, so I create one now.

When Max converts a music file containing album art images, it also converts the images, to png format. The result is a larger image than the original jpeg for instance.

Please just keep the image data untouched.

(what's the point in trying to tweak compression ratio in order to load as much music as possible on one's iPhone, if one loses 2 GB at the end because of enlarged image data?)

Thanks
