Is this for internal use? Like for marketing purposes? If so, Marketing needs to do this. A more suitable area for that would be a Github repo (backed by Google Drive for larger files) for marketing purposes exclusively rather than publicly accessible on the website.

Else, if purely improving ACM's public branding on the website, that may be more suitable for the About page. Open to discussing ideas though with regards to this.
