Here's some things to look for to see if IH is working ... keep in mind that IH won't resize the images if it doesn't need to.
Right click your images and look at the properties ... if the image is being pulled from the bmz_cache folder IH is working properly.
If your referring to the medium image zoom, the full functionality of that was never finished by the developer and therefore won't zoom your medium images.
Small Images are used for areas such as your sideboxes, Medium Images are your Product Info Images, and the large images are what you get when clicking for larger images. Listing Images can be set independently, but keep in mind that if you want the Small Image Zoom to function your Listing Image Dimensions must match your Small Image Dimensions under Configuration :: Images. Also, the size of the image you get on mouseover is dependent upon the size of your Product Info Image (Medium Image).
The best and easiest way to work with Image Handler is to let it do the work for you. In otherwords, upload your highest quality image when adding or editing a product and IH will generate the images for use in your cart (small and medium). Now of course, if you want different images for your small and medium images you'll need to utilize the IH manager so you can distinguish unique images for a specific product.
If your looking for some other image effects look into the HoverBox mod in my signature. It's compatible with IH2. Just make sure that IH is installed and working properly first.
