As a backup, not to show them (Flickr doesn’t support raw).
From Avar: “You can upload RAW to flickr, you just rar pack it and append it to the end of the JPEG file. Then you can download the “original” version from flickr (the sha1sum will be the same) which has both the JPEG and the RAW file (and anything else you’d like to stick in there) in the appended rar file. I have a script I use append RAW/Metadata files via RAR files to my generated images before I upload them to flickr with flickr-upload“. photo credit: ♫ Vky
