Silly me.

It seems zencart works to enlarge images in its native state anyway, as it always did. That’s all I want.

I have made a fresh 1.5.3 install into a subdirectory on the server, created a product, and the enlargement works perfectly well…here..

Since that is all I want to do, it seems IH4 is superfluous.
IH4 is hardly superfluous. It provides a rather useful purpose and that is to optimize images (thereby improving site performance) in addition it adds features which aid in facilitating the process of managing and uploading product images.. Now if you don't want these features, then that is a personal choice, but superfluous implies the module serves no useful purpose, and I wanted to clear that up..

That said it now sounds like you had a pre-existing issue with the image enlarge function. Sounds like you thought IH4 would fix this issue.. IH4 would NOT have fixed this as IH4 doesn't modify Zen Cart's native image management or the behavior of native functions.. (Doesn't modify the image enlargement function AT ALL) IH4 instead ADDS additional features which only work when the native functions are behaving as they should.
