This software can download the pictures and videos: it's quite remarkable because there are free alternatives that pretend to do so, but in fact don't! Note that 4K Stogram is limited to only two accounts from Instagram, unless buying a serial number. It's cheap but if you've already downloaded a lot of stuff on your drive, 4K Stogram becomes really very very slow; sometimes it stops responding too (on Windows 7 Pro 64, 6 GB). An easy and free way to download from more than two accounts is to play with the file .stogram.sqlite (considering the small cost of a serial number, I'd prefer to buy a serial). This software must be optimized or it should be completely free. For example, there's no need to make and save big thumbnails later reduced to smaller pictures viewed in 4K Stogram (in my opinion, it's simply dumb).

Upon clicking their link to view source code, it 404s. The application itself works fine, but does require a license that costs $10-20 if you want to subscribe to more than 2 accounts at a time.
