Please help me (SLUB high quality images for possible PDF)

[JCH]

I am at my wits end as to what s going on with SLUB Dresden, that is, the Saxon State and University Library and it's "new", or default as I can no longer find the previous DFG viewer - about 3 days or so ago, every SLUB manuscript in the viewer went from producing very high quality images to low resolution blurry with a ugly bar on the bottom of every page (I've attached a image as an example, though got a error so might not show).

I tried to find a work-around using this method on this very site, but it gets stuck and does not work:

Anyone have any solutions...? I am quite desperate... in particular for Jan Dismas Zelenka's oratorio 'I penitenti al sepolcro del redentore' in particular,
for a project I am working on...

Suppose you are are p.10 of this score. If you click download, Einzelseit herunterlagen (jpg) you arrive on https://digital.slub-dresden.de/data/ki ... medium.jpg
which is a 1000x790 page. If you change medium into large you obtain a 2000x1581 page which you can download. I don't know how to provide a larger image. Hope this helps.

That is what I've been doing, but the results are still very blurry, however I see no option to change "medium into large"..
