Slideshow view in folders

[Pikthulhu]

This doesn't seem like a very advanced thing, so hopefully someone has an answer. In a folder that has mostly pictures, there is usually an option in the 'view' tab for viewing it a s a slideshow, but for some reason it randomly enables and disables itself and often it will not allow me to select it, even when the folder has only image files in it. Can anyone give me some insight into how I can keep this feature on all the time?

open a folder, (windows explorer) go to tools, folder options, view, put a check in remember each folders view settings. apply, now if you change any other folders, dont apply the settings to all folders.
