[Pharo-project] Image size

Hi, I have one of my development pharo image with 103 MB of size. Is there an normal image size on Pharo? I clean my system orphan instances and WARegistry clearAllHandlers but it continue with that size. There is on Pharo any tool like to Space Breakdown Chris Upal Dolphin Package (http://metagnostic.dolphinmap.net/SpaceBreakdown.html)? Thanks you, Facundo
