Love the concept and the minimal permissions. This would be the replacement for QuickPic except for 2 issues▶ ① It doesn't display all folders that contain pictures (they are not hidden). They are shown by other galleries  and shown by Simple File Manager from the same developer. I've noticed that if I use a file manager to select a picture file from a folder that Simple Gallery doesn't show  and choose to open it in SG  after this the folder miraculously appears in SG with all its pictures. ② Sort by 'date taken' not working (orders to 'date modified').
