Invalid filenames can work sometimes in zencart (without IH3) installed, this is because zencart doesn't process or handle the image, it just passes the name straight to the browser, whereas image handler runs the image through optimisation and resizing functions and these invalid characters can cause issues with php as some of them have special meanings in php.
There is info on this in the IH3 documentation and also through out this thread
Issue 2 when you view these in imagehandler, what colour are the additional image filenames showing up, black or red? if they are red it means there is something wrong with the file.
