Bottom of web source dialog:
Save image to tag - checked
I have changed nothing in file system, because everything works very well.
WMP (Now playing mode) shows covers for files tagged with discogs script.
WMP (Now playing mode) shows covers for files tagged with BP script except for files tagged in last month.
VLC and winamp shows covers for all files anyway.
When I manualy add picture from BP and save tag, wmp doesnt show the cover again, except if picture from other source is.
I think it's case for X-files
