I tried Picaloader and Mihov Picture Downloader.

For exemple: I want to download all the part of this image:
<http://zoom.artsmia.org/fif=/mia/fpx/46/mia_46702b.fpx&init=-1.3604652,0.0,2.360465,1.0&rect=-0.43023264,0.0,1.4302324,0.5&wid=640&hei=480&lng=en_US&enablePastMaxZoom=OFF&bgc=85,85,85&page=mia-basic-zoom.html&obj=uv,1.0?319,176>
