Many images inaccessible

Hi, thanks for this great work! I was trying to download the dataset and ran into issues with many of the images; it seems they're no longer accessible from the provided URLs. Specifically, 63/540 of the images were not downloadable, which is more than 10% of the dataset. Could you provide an alternative link for these images to allow apples-to-apples comparison with your work?
I've provided the problematic URLs and their indices in the provided JSON below.
