So, dropped the product image zoom version of the above. Instead went with incorporating the existing zoom functionality of IH4, which I know Diva you dislike... :)
Recommend adding to the IH4 installation package (and associated SQL) the following file:
includes/templates/IH_INSTALL/templates/tpl_modules_main_product_image.php
<?php

<?php require(DIR_WS_MODULES . zen_get_module_directory(FILENAME_MAIN_PRODUCT_IMAGE));
if ($products_image != '') {

$newimg = handle_image($products_image_large, addslashes($products_name), LARGE_IMAGE_WIDTH, LARGE_IMAGE_HEIGHT, '');
list($src, $alt, $width, $height, $parameters) = $newimg;
$products_image_large_test = zen_output_string($src);
if (file_exists($products_image_large_test)) {
$products_image_large = $products_image_large_test;
$newimg2 = handle_image(DIR_WS_IMAGES . $products_image, addslashes($products_name), SMALL_IMAGE_WIDTH, SMALL_IMAGE_HEIGHT, '');
list(, , , , $parameters2) = $newimg2;

}

The above does not require any additional switch to turn on/off the zoom functionality as it is auto controlled when it comes to the builtin zoom functionality.
As for the other code to co-work with what cvhainb put together, well, the constant to check against is:
ZOOM_SMALL_IMAGES
and can be anded (&&) with the file_exists check above for the auto_loader file in each of the single lines.
If it really becomes something necessary to post, then can, but above uses the hover on image to enlarge
feature of IH4.
Peace.
