Hi Nishargo, thank you for looking into updating the links in the repository.

A couple things to note:

1. The links that you have provided with the uploaded images point to your fork of the repository (https://github.com/Nishargo/NeuroKit/) which would add some inconsistency to the readme.
2. I am unsure if hosting the images of the university logos would be a good decision as they are copyrighted and most likely would not be compatible with the MIT license of this repository.

Therefore, it would make the most sense to update the university logos based on the URLs that they provide (or wikipedia or otherwise), such that we are not directly in violation.

Thanks again for your effort!

Hi Johannes,

Thanks for taking the time to look at it.

You do have a point...but currently the images are breaking. I tried some other options, as they didn't work, I tried the last option to make a folder of the images and reference them. I will see how I can still make the update keeping in mind the MIT license and copyright issues.
