>Always post the actual command line used (log file line two)
I was not sure which is the right line two, so I'd better post both
possibilities

etc. (string of website names)

I changed the link name slightly, since I don't want to post my picture
hosting website including id.

>> I don't want any subfolders at all, I simply want
>Site structure = xx in web/xx
Sorry, I did not find "site structure". I do not have the least notion what I
did different than last time, but this time all the pictures are in one
folder.

Now for the name of the picture
>The image name is what the site named it.
>If the url is something like getImage.php?ID=BOAT you could use HTTrack
Help:
>User-defined structure
<http://httrack.kauler.com/help/User-defined_structure>
>to name the images b4bc_1be45-BOAT.typ

OK, I called up Set Options > Build > Local structure type
And found a list of naming options. I finally chose Html in web/html,
images/other in web/images

As a result I got snippets of the url name, enough that the name was with
difficulty recognizable in most cases. I made another attempt and chose Set
Options > Build > Local structure type > Options %N	Name of file including
file type (ex: image.gif)
As a result the files were stored in a strange format I don't know what, but
the pictures could be opened with picture programs, though I was missing the
usual picture preview in the file folder.
However the picture name was still not the full url but only some small and
not always useful part of it.

Now if only I could get proper names – either the complete url or a name to
upload as a text file together with the picture urls, I would be completely
happy.
