We have added option in Tools menu “Copy Pictures” in version 6.10 where you can copy pictures between picture tags. Now you can copy Front Cover to Others(iPod, iTunes) or vise versa for all 15 picture tags.
In General Options you can check check boxes if you want to download picture to Cover Art or/and Other picture tag. That saves a lot of valuable space for iPod users, because they don’t need to save the same picture twice.
Once again thank you for your suggestion.
