3GB is quite a reduction - presumably you've eyeballed the files and are happy with what will be removed, although it's a lot to check thoroughly. If you want to keep pictures you will need to set "@prune.retain.pictures=yes", not sure if you've done that or not. Picture previews (prune.retain.previews) is enabled by default, but the cached versions of the pictures are not retained by default (debatable whether they should even be in the cache, or if you'd want to keep them when pruning is all about trimming away the crud, and the pictures could huge).
