I guess for smaller collections this isn’t an issue, but on our collection of 16GB images, Omeka appears to be creating a 2.8X file footprint, between /original, /fullsize, /square_thumbnails, and /thumbnails.
As far as I can tell from clicking around the interface, the /original files are not used in the web presentation? Can someone confirm if it’s safe to delete them?
After googling this, I saw a thread about original filenames and downloading from admin side, so for my purposes I don’t care about re-downloading the files from within Omeka (maybe that is why /original is stored?).
