I have downloaded hundreds of DVD iso images with wget and curl during the past years. I had maybe one or two that were corrupted in one way or another, mostly because of improperly configured (windows) webservers. >4Gb with HTTP is no problem nowadays, FTP isn't either. If you have doubts about HTTP/FTP you can always use the Bittorrent way to download (also with commandline tools like btdownloadcurses or similar). It doesn't really matter when you download them although in some cases it can make a difference in speed to download overnight but with most tools you can also specify a maximum bandwith to use. To be sure an image is ok you can always check the image with the md5/sha1 checksum which is normally found in the same directory as the image on the HTTP/FTP server. kind regards, Michel
