Maybe the embedding with .png explains why, cause Twonky only accepts .jpg as image format/suffix in order to show album art.
Sounds like it, then.
It's unfortunate - my guess would be PNG was chosen, because the FLAC site advises to use JPEG or PNG on account of compatibility. But from what you're saying it seems there's stuff that's not compatible with PNG.
I'm not going about this very scientifically and haven't tried other ripping software yet being satisfied with Max so far.
I suppose the alternatives - unless you get into MacPorts or virtualization software - are iTunes and XLD (X Lossless Decoder). But you can't encode to FLAC with iTunes. If you want FLAC the choices are limited on OS X.
I don't know what Max does to the art if you rip and encode to Apple Lossless in iTunes and then convert to FLAC in Max. But that would be a long way round, anyway.
Or the thought occurs that you could rip and encode in Max and add the album art with a separate tagger. But, again, the options are limited on OS X. The last I looked Media Rage could, if I'm remembering right, add images to FLACs but only one file at a time, not as a batch like it can with MP3s. You might try their tagging software and email them if it doesn't do quite what you're looking for. They seem very responsive to customer feedback - I suppose they have to be if they want to stay on top of their market.
I'm thinking that while FLAC is quite well supported across platforms, it's not of any particular interest to many Mac users, so there's enough software to be going on with but not quite full coverage of everything you might want to do. I suppose iTunes in general does so much of what most people want, and more, and does it so well, that most Mac users just accommodate themselves to it. Here, this would mean they use Apple Lossless instead of FLAC.
Sorry. All I can think of is try XLD or rip with Max but try tagging with Media Rage.
It may be possible to add a JPEG at the commandline, but I haven't looked into what commandline tools a user would have to compile/install for that.
Maybe someone more knowledgeable than I would have better advice, but these boards seem very quiet at present.
