Hello!
I have now shared how to download eNSP, the images for eNSP and the images for EVE-NG, as I was told that separate posts were unfriendly for you guys. So, I've collected all the download links in this post and hopefully you can find them easily now.
If you can't find the requested images, please comment below and I'll try my best to get that for you!

HOW TO EXTRACT THE FILES
Download all the files to your local PC and put them in the same folder.
Extract all the download files. You can get the same number of files named xxx.partx.txt.
Rename these files as xxx.partx.rar.
Extract the file xxx.part1.rar to get the image.
