First thing I would do is to right-click on the folder that contains the pictures and then select Properties. On the dialog that comes up, select the Customize tab. There is a dropdown box there that you can select to tell Windows what kinds of files are in that folder, in your case select Pictures.
In addition, in any folder, you can change the view and select how you want to see the files listed. In the Upper right hand area of the Explorer window there is an icon that looks like boxes with lines next to them. If you hover over that icon it will show "Change your view". If you click on the icon, each click will cycle thru the available views. On the side of the icon is a down arrow. If you click on the arrow, it will bring up a list of the various views you can select from.
