I think some of the images listed in the dataset are no longer available online

[Pedro F. Proença]

They are all available! I just confirmed it.

Sometimes the servers hosting the images can be temporarily unresponsive or assign you low priority, leading to Timeout.

You can always download the images from here: https://zenodo.org/record/3587843#.YB3RupNKjow
