This app's caching mechanism is great. First time caching is slower(2-3 secs). You can choose from four background themes.
Features:

-Inapp Password protect hidden folders.
-Share to app list reorders automatically according to most used option.
-Basic editing functions(rotate,crop,resize).
-Stack,grid,list,explorer view modes.
