This is a problem if I have limited band and the picture is very great (i.e. 20 MB) Reproducible: Always Steps to Reproduce: 1.go to a page with a big picture, for example http://antwrp.gsfc.nasa.gov/apod/image/0806/coma_hst_big.jpg 2.wait till the picture is downloaded 3.right click the picture 4.click "Save as..." 5.choose a destination name on the Save file dialog the download restarts Actual Results: the image file is re-downloaded Expected Results: it should at least be cached, if the picture is kept in memory in an economic format, so that the download manager understands it has not to download twice, at least for these big big files.
