The first thing you should do when you expect leaks: flush
the ZODB cache. Look again at your reference counts.

If you still see large reference counts, then you probably have a leak.
If not, then probably not.

Especially, if your image count would go down, then it would probably
mean that some of your persistent objects have images as
volatile attributes (e.g. in various scales (thumbnail, lowres, ...)).
