Hello again Grazia,

As it happens Wikipedia has a copyright template which recognises authorship. I will apply this, on your behalf, to images pkf 1, 2, 5 and Berkeley. Again, and sorry for this, I will need your approval. The copyright for each image will then read:

"This image is copyrighted. The copyright holder allows anyone to use it for any purpose, provided that acknowledgement is given to Grazia Borrini-Feyerabend as the creator of this image."

From: Grazia Borrini-Feyerabend

Hi Chris,

Fine with the copyright as you phrase it. I append my signature so you can see about my work.. You can also look at my name in the net. Best,

Grazia
