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.
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-
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_
fusk http://mdz10.bib-bvb.de/~db/bsb00007894 ... b00007894_
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.

If you have any questions, don't hesitate to ask.
