Integrate new images of GSA 25/W 2890

[gerritbruening]

• Transfer new images to the image server
• add graphic elements for each image in the documentary transcripts
  We would need to keep the present images since these are used in the TIL.

@thvitt, all original Tiffs are stored somewhere, aren't they?

For manuscripts, yes; they are on the server in Würzburg.
