You don’t need to test on multiple platforms.  It is in the nature of the beast that if the 32-bit result of a conversion starts up at all then it is correct and will function on all platforms.

The image conversion does not do anything special which could possibly affect cross-platform behaviour.  Its effects are entirely below that level, simply changing the width of all pointers and mapping out-of-range immediate into their boxed equivalents (SmallFloat64 => BoxedFloat64, SmallInteger=>LargePositiveInteger & LargeNegaitiveInteger). Just as the 64-bit product goes the other way.  Nothing else is changed.
