Cannot add artwork ?

All my attempts to add artwork in itunes have failed and i believe i have tried everything obvious it really is bugging me everything was okay previously now nothing happens or maybe it's there for a second and when i come back it's gone GRRRR

 

Still struggling

Yes this is the way i have been adding artwork, but i have tried get info etc fixing permissions using a smaller image i am at my wits end as to what the problem is. Anyone have this problem before ?

 

Fixed

I tracked down the problem as the new version of CD spin doctor that i use to record my vinyl. This comes with toast titanium 9. If i convert the tracks to aiff in itunes (although i thought they already were) the artwork can be added. I hope this helps someone out in the future

 

Hmmm

Do You have the latest version that comes with toast 9 ? Its very strange i was sure i found the problem ! I export active tracks to the desktop in aiff format and then import these into itunes. Perhaps i am doing something wrong ? I know if i convert them again in itunes to aiff they get a little smaller and then i can add artwork. Perhaps this is a permissions problem ? Either way i'm baffled !!
