Great tool. I originally downloaded this for IG because it was able to download full-resolution 1440x1800 images without any issues, but recently it hasn't been able to do that.

A different app is able to see the 1800x images if I select an image only on my timeline, and if I go incognito mode and select the images on their profiles. It's called "Instagram Photo Plus" if you're curious.

However this app has still been fantastic when I'm on other websites, especially when I grab an extremely scaled down image from a web article but then it auto-links to the high-res original photo.
