The memory isn't released immediately because Emacs caches images for
better performance. And even if Emacs does free the memory used for
the image and its buffer, it doesn't necessarily return that memory to
the OS; that depend on the build and the OS you are using.
Try the command "M-x clear-image-cache". If that helps, you may wish
to customize your value of image-cache-eviction-delay.
