I'll send a patch.

Yes, the idea is to add an org-link-parameter named ":preview" so each
link type can register how it should be previewed.  When omitted, we
fall back to a default (only for file links) that's the current
image preview behavior.

More fine-grained behavior may be desired in the future -- for example,
web url links to YouTube should be previewed differently from web url
links to arXiv, but for now this will be the responsibility of the
single :preview function in org-link-parameters.

Would you like this to be part of org.el or should I spin out an
org-image-preview.el feature+library?
