is there a solution to the 404 error?
I also uploaded the zip file on amazonaws and added the CORS rules accordingly to my bucket.
This is the link to my experiment: https://expt.pcibex.net/ibexexps/Potsdam-experiments/Chai/experiment.html
And this is the link to the zip folder: https://chaipictures.s3.eu-central-1.amazonaws.com/Pictures.zip
If amazonaws is not usable for preloading a zip-file with images, could you recommend a webserver where I can rent storage and which allows cross domain request?
