NV mp3 tags and artwork

I have about 300 or so songs on my MicroSD card. I used tag&rename to tag them all for my phone. Now they all show up with a question mark in front of the artist, album, and song on the phone. But, not on my computer. I'm confused.

And I can't get artwork to show up either. I resized it to a 200x200 jpeg which is what the size is when you purchase using vcast.

Any help or ides????

Thanks in advance,
Andrew
