I've made a Python script tool using ArcGIS Desktop 10.0 SP2 and have accessed its Item Description to Update its Illustration by browsing to a *.png file. The expected Illustration then appears in Item Description.

However, when I use the Catalog window, to access Thumbnail view of the Toolset in which that tool sits, the Illustration does NOT appear as its Thumbnail. Am I perhaps missing a step?
