Album art for podcast won't load

[fillilutten]

I'm setup with a lot of podcasts. But none of them is fetching the album art work from iTunes. I've tried to go with the "Get image to album" or whatever the option is called. But nothing happens. As i understood it it's something in the code that the podcast producer have to do for me to be able to download the album art. BUT i mean, since everyone of my podcast has their album art perfectly clear in the iTunes Store it self it should be working, right?

edit: Yeah, and also. If i download the same podcast via the iPhones iTunes Store it works perfectly.

Thanks so much in advance, have been trying to fix this for a long time but no success.
