You can download all images from

please note that their compression code (which is on GitHub on the link I posted initially) does not produce a jpeg compliant image. It is compressing it to a format that is smaller than the original jpeg and then you can run the tool again to convert the image back to a jpeg. the result of the decompression is byte to byte identical to the original jpeg.
I was thinking of using both algorithems (i.e. ImageOptimizer and then lepton) to reduce the files as much as possible on the disk
