949757 - Modify Gallery to not save image previews to /sdcard/.gallery

Status: RESOLVED FIXED

(Firefox OS Graveyard :: Gaia::Gallery, defect)

Description

[David Flanagan [:djf]]

When bug 854795 lands we'll have a way to efficiently display a large image at the size of the screen without using a ton of memory. So we will no longer need separate preview images for each photo.

We'll want to modify the metadata parser so that it no longer saves preview information in the media db. And especially so that it does not create and save preview images to /sdcard/.gallery/ for photos that do not have an embedded EXIF preview.

Note that there is a data migration issue here.  We may want to upgrade the DB to remove the preview fields from the records and at the same time delete the preview photos in the .gallery/ directory.
