Ok here is the quick and easy way to get many online manuscripts. It uses a program which I suspect was developed to download porn galleries.
go to
http://www.urltoys.com/
and get the installer (left hand side column).
Install and follow instructions.
What you will need to do is find out the range in the series of images. Then create a .flux file in notepad. Make sure you select 'all files' so it doesn't save it as a .txt file. The command line in the .flux file should be something like-
flux
http://thisistheurl/whateverdirectoriestheimagesarein/[imagestart-imagefinish].jpg
What goes in the brackets is only what varies between image files, ie. for these Mair manuals it is [00001-00626] and not [bsb00006570_00001-bsb00006570_00626] which are the full filenames for the images.
the command line for these Mair manuscripts are-
fusk
http://mdz10.bib-bvb.de/~db/bsb00006570 ... b00006570_[00001-00626].jpg
fusk
http://mdz10.bib-bvb.de/~db/bsb00007894 ... b00007894_[00001-00616].jpg
So install the url tools, create a .flux file for each of those command lines, then double click on those .flux files and then click go and it will start downloading.
A word of warning though- some online manuals can be very very large. Note these flux files are also for the 150% versions of the Mair, so you can take out the /150/ if you want the smaller version.
Here is the flux command for Lecküchner.
