I put a website together to showcase a bunch of images of the New Testament Papyri:
http://www.earlybible.com/
It has most of p46 and a bunch of other papyri, most images in high resolution, and the site is formatted for easy viewing. It even has a built-in magnifier

I think it's important to actually SEE the papyri for oneself because, as the site says, if you never saw the first page of P46-Ephesians, you would think it was a big deal that P46 is the earliest manuscript that leaves out "ἐν Ἐφέσῳ," but when you actually SEE the papyrus, you can't help but notice "PROS EPHESIOUS" written across the top of the page!

Let me know what you think!
