My zip file contains one image named 0001.jpg (I've also tried with the same image on .png format) and one .txt file named "DATALINK.txt" where I've listed several biblionumbers and the image name separated by a comma; one biblionumber per line.Like this: 26794, 0001.png 26795, 0001.png ... and so on. ... The error in my intranet.error.log says the same in both installs.

I'd suggest to remove the space character in your file ""DATALINK.txt", so the content will look like: 26794,0001.png 26795,0001.png ... Hope this helps.
