Hi,
I like to download lots of pictures from tumblr and save them onto my phone for later viewing.
But a couple weeks before, I noticed that a lot of the photos were missing from the gallery.
I first saw them when I saw trying to clean up some space with an app called Clean Master.
it says it's in a folder called .thumbnails but I can't find it anywhere.
I've searched online to see if other people have encountered this problem, but none were very helpful. (I tried quickpic but nothing really changed)

Here are some photos....

I can't view photos in gallery but I can still see them through gallery thumbnails-screenshot_2014-01-08-16-06-10-1-.jpg
These photos aren't anywhere in my gallery.

Apparent location of the photos

is there a download button somewhere?


To summarize that:
- some of my tumblr photos are gone and I wish to retrieve them
- i can still view them but only through an app (clean master)
- can i access these photos from my phone and place them into the right place?


Please help if you can. Thank you so much.
