Instagram Mass Downloader of FULL SIZE Images?

Any way, preferably for free, via desktop, to have all images from an account you like downloaded in their FULL SIZE to your desktop? Videos too, if possible, but definitely images. To where you input a user's handle or visit their page, click a button and the software or program downloads all images from their profile in full size? An app for Chrome that does this does it only for individual pictures as you open them up and only works for like 1 out of 3 pics.

Thanks.
