Everyone probably already knows this but once you have a bunch of jpegs the right size you can make a bat file that will rename all the jpegs to a metadata extention. BTW I am running windows 7, not sure if it differs on the older os’s.
Open notepad and type the following
ren *.jpg *.metathumb
save this notepad as metadata.dat
save it to your desktop or working area
put all your jpegs into a folder with that file and run it.
it will change all of the extentions to the metadata format.
I have been doing my cover art by hand for the default view and this has saved me a bunch of time
