When I go to upload an image to a website, to load an image into gimp, or really anything that has to do with me opening a file in explorer through a non Microsoft application.. I only see the file names and not the images!

In the normal file explorer I can see Images fine, but when using explorer from a website or application when trying to upload / download, I cannot see images.

Here I have listed 3 Images.

Quite obviously, this is extremely annoying ..
and if anybody has a solution to this problem I would be extremely grateful. :)
