is it really necessary to open a brand new thread each time one runs into such a trivial matter? on the other hand, if it was regarding a serious matter, i could totally understand.

anyway back to your issue. perhaps you could first make sure that the album art is actually present for each track (copy and paste the respective picture to the bottom left corner, manually or advance -> get album art)

once that is affirmative, unsynchronise and remove ALL the tracks inside your iPhone. you can now, add and synchronise all the desired tracks again.

You can try this:

i) In iTunes, select all mp3's and right click. Select "Get Info".
ii) Search Amazon.com for album cover. Right click on cover and save to desktop/folder or drag and drop the album cover to Artwork. Done

what i did is, for every album/song i have, i searched for the album artwork via Google, one by one. yeah it might be a very troublesome task but there's no problem looking for them, even for old songs. (my whole music library is in English). trust me, Google is the best source. just make sure you did searched thoroughly.
