I took a quick look at "www.ladies.de/Home" - for research purposes only, of
course.

The content of a webpage is comprised of multiple url/files, which your
browser downloads and displays. In Firefox, to view the url/files that belong
to the current page, goto Tools-->Page_Info-->Media_Tab. 

From there, I can see that any links to "bilder1.ladies.de" are to image files
only, no html files. It appears there are no html files on that domain that
httrack can parse. 

The purpose of httrack is to download html (and css) files, and parse them to
find more links to download. Httrack doesn't find and download url/files by
magic - it can only find them by parsing new urls from html files etc. that it
has already downloaded. So at the very least, the url you provide to httrack
should point to an html file or similar. And then, God-willing and with the
correct filters and options, it will parse more links and download them. So at
least provide httrack with an url that you know will load in a browser.

Again, an flv file isn't a file that httrack can parse to find more urls to
download/parse. If it parses an url to an flv file, it will download it I'm
sure. But an flv file won't help httrack find more urls on the website.

The logfile wasn't that helpful. Your url didn't point to an html file, so
httrack had no work to do, and shutdown immediately. Indeed, I suspect the
server at "bilder1.ladies.de" contains only images - so no html files for it
to parse there.

To httrack those images, you might start with an url like
"www.ladies.de/Home". But looking at that webpage, it looks very complicated,
probably with javascript and dynamic scripts in the background, fraught with
difficulty.  The more complicated a webpage, the more tricky it is to httrack
it. You may need to swot the httrack guide on filters - not trivial. Perhaps
you should try using httrack on something simpler for a first project, eh?
Lastly, I believe there are firefox addons that let you download all the
images on a webpage. Or the Video DownloadHelper addon to download flvs.
