The image is successfully resized, but it fails here.

Probably this is a bug in pngjs package which seems not to be maintained anymore. So, a code refactoring is needed. Related to #2.

@izuzak I remember this bug appeared when we met in Zurich, but I hided it by manually downloading the file and saving it in another format. :smile:
