I updated Ovi Store client to version 1.22 (14) on my E72-1 and I also noticed that all navigation images remain the on the phone memory and are also displayed in the gallery of images. I also manually removed all images dumped from OVI store client, but the application starts to malfunction and still fills the memory.
A newer version of Nokia Store client 1.22(15) is now available for manual download on Nokia Store. It removes all files from the folder imagecache/Jupiner.
It does not remove the folder Imagecache/Jupiner, only remove files. After you have installed new version of Store client, Gallery does not display the cached images anymore.
This is not a forced update. You need to search Nokia Store to find client on Store.
