As you know, the creators of the Instagram service did not provide any built-in tools for downloading the pictures you like. This is done in order to prevent the violation of other people’s intellectual property, which are published photos.
However, this restriction can be easily circumvented. To do this, open the page in the Google Chrome browser with the picture you need, and then right-click and select the “View Page Code” command.
Before you in the new tab appears html-code page. Press Ctrl + F to display the search string. You need to find a file with the extension jpg. The first result on the page will show the required link. Just copy it and open it in a new browser tab.
After that, you only need to save the picture to your computer. You can do it using the context menu, in which you should select the “Save picture as” command.
As you can see, downloading your favorite photo from Instagram is very easy. To save the video, you should act about the same algorithm, only search for files with the extension mp4.
However, it is worth remembering that all works published by other people are their property. Therefore, one should not even try to use them in their projects, articles, presentations or for profit.
