Change the images to more meaningful ones.
Right now both the SVG Icons from the
subnav.html (Sub Headers) are the same from the
gtk-web repository, and most don't fit the context of the pages they were given.
We need to create/design new Icons that could fit that.
Also, the images that are used in the sections of each page were mostly chosen from the GUADEC 2018 and GUADEC 2019 photo albums. I believe they may need to be changed.
@ravgeetdhillon would you like to contribute on this?
