How to download all Instagram Pictures of a specific account as a ZIP file.
That archive includes all of the photos.
Step 1: Install Google Chrome
Step 2: Download this plugin
Step 3: Open the instagram user profile
Step 4: Press the button on the top right (black/white arrow down)
Step 5: Wait and after a while the download of the zip archive starts
With that way you can easily get all of the pictures in the best quality. Other solutions doesn’t offer a bulk download. That is pretty annoying if the account has 100-200 photos.
