Media Bay Images question


in Mediabay in Audio - Properties i try to use “image” to get an idea of the content in search results.
But it seems that each time i open mediabay the images are under construction. even when finaly they are visible (takes time) next time i open media bay images are forgotten and back to “under construction”
makes it useless.
is there a setting somewhere ? to make sure images are stored with/next to the files ?
