when I modify the parameter it appears my scalar reference suddenly maps back to overloaded sub instead of the original, thus creating an infinate self referencing call

I am taking an educated guess, but I think this is because mod_perl runs your code in a persistent environment. It does not "restart" each time. Once you override the WSC::Image::list_images subroutine, it stays like that. Then the next time your code is called, you take a new reference to that subroutine, which is still overridden by your own sub. Thus, the infinite loop.

You need to work out a way to store the original subroutine reference once and only once, then use that reference every time. Perhaps you could get this working with a BEGIN block, but again, I'm just taking an educated guess.
