Ok, I see,
I don't know LCL good enough.

but 2 ideas that may or may not help.

If you know the unit in which the handles (the missing of which causes 
the crash) are destroyed, then add it to the uses (interface section) 
clause.
My understanding is that a unit's intialization,  should be called after 
the initalization of all used units.
For finalization, imho it should be the other way round; your unit 
should come first.

If not, or maybe easier, can those images not be destroyed by a 
component which is owned by application (and therefore gets freed at 
that time)?
