How to download photos (of others) from Instagram? I already saw this question but I can not see the files 0.'s is possible?
I don't think this is possible by default. If your device is rooted, you might be able to inspect your file system, and find where the pictures are stored (and then, you might be able to actually view them, depending on if there are encrypted).
Bottom line, I don't think Instagram wants you looking at their pictures, outside of their app, and you will need to bypass their controls to do this.
