Where are all the picturess if you change setting back from .nomedia to store in gallery?
The .nomedia option hides all items from the folder to which the file is copied. If you remove the file and then restart the phone, the Store folder will appear as normal in the Gallery app if you have images or any other compatible media files. Howeverm I recommend installing an application that deals with these type of operations.
One such application is called Gallery Lock: https://play.google.com/store/apps/details?id=com.morrison.gallerylocklite&hl=en
