Specifically, in mobile it is very easy to accidentally tap an image and unintentionally download a large resolution photo. It's also not clear from a UX perspective what clicking on it would do.

Some of our users have limited data plans and this can be quite costly for them. Given we have an original file link it seems surplus.

In extreme cases, downloading a multi gigabyte file on desktop is sometimes not fun either. Certain very large jpg files have been known to crash certain browsers.

True dat.
Personally I would advise just removing the link.
If it's a widely used feature maybe this should be a gadget/user preference but let's remove it and see what complaints if any there are.

Providing a link to the original by default is integral to our pursuit of free knowledge. It will not be removed.
