Need help with an image url

Hi,

i need to process an onix file (kind of xml). This was no problem, but in this onix file the images belonging to the products are a link to a script. When i open the url in my browser, automatically the image is downloaded to my pc. 

What can i do to use this link and save this image on my webserver? I tried file_get_contents but i did not succeed...

This is an example of the url:

https://cbonline.boekhuis.nl/pls/cover/p_get_cover_fe?p_hash=9C099FC9E2626377495DA02FD7F802B0

Thanks.
