I couldnt find the way to create folders on QuickPic. I did this on Astro File Manager. Just create new folder and move the pictures to that folder. It was actually very simple.
Then on QuickPic, the folders I created appear as different albums. All those pictures on the 100Media folder are shown in the camera album. The other folders are on the DCIM folder. The stock gallery app didnt recognized this new folders.
