(to install the userscript, make sure you have a greasemonkey
compatible userscript manager like tampermonkey installed. if chrome says "invalid script header," you didn't install
one) image viewer+ is a userscript that adds some features to the browser's
image previewer.
why?

compared to chrome's regular image viewer, MY viewer is better in a lot
of ways:
- chrome and firefox caps zooming at 500%. image viewer+ can zoom in
and out past its breaking point.
- if you're looking at some low-res pixel art, just set image
rendering to pixelated.
- click and drag to move the image, and scroll to zoom (you can also
quickly turn this off, just in case you need to drag-and-drop the
image somewhere)
- everything you can do with your mouse, you can do with your
keyboard.
- zooming in on the image doesn't apply to the rest of the website.
- you can rotate and flip the image.
- i love you
that's mostly it. but really, all of this really goes a long way.
